The deputy chief executive of oxfam has resigned, following allegations the charity tried to cover up the full details of a sex scandal in haiti, involving its aid workers. Senior figures in the organisation, have been meeting the International Development secretary, after the government threatened to cut millions of pounds of funding over the controversy. The charity has been asked to produce all its evidence relating to what happened with some aid workers after the haitian earthquake in 2010. Our special correspondent lucy manning has the details. The allegations that the team knew, about prostitutes being used not just in haiti, but in chad, with nothing done. She worked in Human Resources in haiti for 0xfam for two and a half years, says she flagged concerns and was ignored. There was a lot of rumours on the ground about management and leaders exploiting the locals, sexually and in other ways, to getjobs, and to have good standing. These were ongoing rumours that would come to me through the drivers and others. On many occasions i would share those rumours with my boss. Now oxfams deputy chief executive has resigned. Penny lawrence was Programme Director whether prostitution allegations were made and ignored. She said, i am ashamed that happened on my watch and i take the responsibility. The actions of their director in chad and arrow mac we re their director in chad and arrow mac were never properly dealt with. Bringing 0xfam into disrepute, enda kenny wait abusing people who may have been beneficiaries. There was a discussion of how the organisation should respond, but we didnt act on it, and more significantly, because there were not formal complaints, we allowed him to move on to another post, and that was our failing. 0xfams bosses were called in to meet ministers this morning with questions over the £32 million the charity receives from the government. Ministers here at the department for International Development no British Charities do good work overseas, but with 0xfam half the story of what happened with its staff in haiti it has now put pressure on the entire charity sector. 0xfam says it investigated 87 allegations of sexual abuse or exploitation last year, and save the children looked into 31 cases of misconduct. Christian aide said it had two cases, one of which was reported to the Charity Commission. I dont think anyone can see in good faith operating in an environment like ours, that we can eliminate all risk as a matter of 100 certainty. What we can do is put on 100 best effort to keep these people out of oui effort to keep these people out of our organisation. The Charity Commission says it receives reports of about 1000 incidents involving safeguarding from charities each year, but a culture of cover up, not the image charities want. Lucy, how damaging is this whole affair, not just a 0xfam but the aid sector in general . Starting with oxfam the resignations following this really dont look good. Allegations of staff using prostitutes in chad, nothing done, then those Staff Members are allowed to go and work in haiti, more allegations, some of them allowed to just resign and get otherjobs, and them allowed to just resign and get other jobs, and the them allowed to just resign and get otherjobs, and the full details not passed on either to the authorities in haiti or in the uk, and the chief executive of oxfam admitting today that the disclosures you heard from that woman in my report, who said she raised them, they should have been listened to, and what we have been listened to, and what we have had from him is an acceptance that although we have at this resignation from the deputy chief executive, that he will also go 0xfa m executive, that he will also go 0xfam think he cant deal with this issue. In the last few minutes from the government we have had details of the meeting they had with 0xfam today. A new unit is being set up that charities will have to do better, and also the secretary of state Penny Mordaunt has written to all the charities telling them they must refer all these allegations to the relevant authorities. Lucy manning, many thanks. Three british tourists killed in a Helicopter Crash in the grand canyon, have been named by police in america. Becky dobson, jason hill and stuart hill, died on saturday evening. Three other britons, and the pilot, were injured. 0ur north america correspondent james cook reports. This is the moment a dream holiday for three british couples turned into a nightmare. The helicopter came downjust into a nightmare. The helicopter came down just before sunset in rugged terrain near the west rim of the grand canyon. Explosions and fire followed with three passengers a p pa re ntly fire followed with three passengers apparently trapped inside. They were stuart hill, celebrating his 30th birthday, and his girlfriend, becky dobson, a receptionist from worthing in west sussex. She was 27. His brotherjason hill who was a lawyer in Milton Keynes also died. He was 32 years old. His girlfriend, jennifer barham, survived. Also on board were jennifer barham, survived. Also on boa rd were newlyweds jennifer barham, survived. Also on board were newlywedsjonathan udall and ellie milward, seen here on the left at their wedding with becky and stuart. They had been saving up for their holiday for a year and three who died had been attending worthing college. They had gone with their passions to enjoy their young lives, going through their careers as they had wanted, to get to this stage in their live and die so young, it is just devastating. In the minutes after the crash passengers and crew from other helicopters in the area rushed to help. They included a nurse. When we finally got some medical equipment down there i started helping with putting in iv lines, then another crew came with medication, so i started administering that, give them fluids to help prevent them from going into shock, kept a really close eye on them and did what i could do. A dust storm meant rescue teams had to walk to the site using night vision goggles. It was more than eight hours before they could be taken to hospital. We could not extract everybody from the crash site until two oclock this morning. High winds, rugged terrain, and as you know, when you fly in treacherous conditions like this, you have to have special training and special people. The grand canyon is attractive because it is untamed, drawing visitors from all over the world. The tour company papillon, airways, flight every year and this crash is the firms second fatal accident here. The three british survivors and the pilot are being treated at this hospital in las vegas. All four are said to be in critical condition. The cause of the crash in the canyon, and the deadly fire, is not yet known. And we can speak to james cook in las vegas now. More details are emerging about the victims . Yes, thats right. Some pretty heartbreaking tributes being paid to these victims. Becky dobsons father peter for example said his daughter was full of life and always happy. Herfriends speak about our beautiful person who loved animals and had a dream of becoming animals and had a dream of becoming a veterinary nurse. Friends of the two brothers who died, stuart and jason hill have also been paying tribute, describing them as popular and great fun. As for here, the survivors are still being treated in this hospitalfor survivors are still being treated in this hospital for these very serious injuries, but the focus at the crash site, which is very remote, is on what exactly happened, why this Helicopter Crashed. It appears the impact was survivable, so why did the fire followed . Why were those trapped unable to get out of that helicopter . Questions for the tour company, for the local authorities which regulate that company as well, and also perhaps questions for the manufacturer of this helicopter. 0k, james, many thanks. James cook, live in las vegas. Theresa may and the irish Prime Minister have been meeting Northern Irelands political leaders, amid speculation that a deal to restore the devolved government at stormont could be close. But negotiations between the democratic unionists and sinn fein have stalled several times in recent months since the power sharing executive collapsed more than a year ago. Heres our ireland correspondent chris page. His report contains some flash photography. The Prime Minister began her visit to belfast at a place which was recently the scene of an unexpected victory, hundreds ofjobs had been under threat at the aircraft manufacturer bombardier. They are safe now after the firm won a trade dispute against boeing in the us. But mrs may came here looking to help find another breakthrough. Northern ireland has been without a devolved government for 13 months. Several rounds of negotiations have failed to break the deadlock between the Democratic Unionist Party and sinn fein. Mrs may and the irish Prime Minister leo varadkar told the parties they were committed to bringing back devolution. After the meetings, stormont politicians struck a positive note. Good progress has been made, we will continue to work to look for more progress. And its about finding an accommodation that recognises the need to respect all languages and all cultures in Northern Ireland. We dont believe that there is anything now that is insurmountable left to resolve. There are matters of clarity and some detail. The main Sticking Point has been whether there should be a new law to protect and promote the Irish Language. For speakers of the tongue, irish is about identity, culture and history, and they believe it needs legal recognition. It needs equality and it needs to be on the same level as gaelic in scotland and welsh in wales. And obviously english here as well. It needs to be on an equal footing with the rest and thats all were asking. But in unionist areas there is suspicion and even hostility towards the idea. Here in Shankill Road in west belfast people are strongly opposed to an Irish Language law. Wouldnt have my children going down schools, you know, learning it, letting the kids learn it. This is british, it isnt irish. Always stick to british. This is a british country, not an irish country. I think its terrible. I think our crews letting us down. That strength of feeling shows how sensitive and symbolic the issue of the Irish Language has become during this long and deep political crisis but there are other disagreements separating the parties including whether same sex marriage should be allowed in Northern Ireland and how the hundreds of unsolved killings from the troubles should be dealt with. The power sharing executive has been in the deep freeze as the issue of the irish border has become one of the most significant in the brexit negotiations. The stormont stalemate isnt over, but there are signs relations are warming. Chris page, bbc news, belfast. The London City Airport remains closed after an unexploded bomb from World War Two was found in the thames, not far from the runway. It was discovered in the early hours of sunday morning, forcing the evacuation of neighbouring buildings. Work to dispose of the device should be completed by tomorrow. The Serious Fraud office is to prosecute Barclays Bank over a loan of more than £2 billion it gave to the gulf state of qatar during the financial crisis. Investigators claim the money was used to buy shares in the bank, which amounts to unlawful financial assistance. Barclays Parent Company was charged with the same offence last year and both firms will contest the allegations. In south africa, leaders of the governing anc party are meeting to decide the fate of president jacob zuma. Mr zuma has been resisting calls to stand down, but over the weekend the partys new leader Cyril Ramaphosa said the question of his position would be finalised today. 0ur africa editor fergal keane is in johannseburg. Weve been here quite a few times in the last few weeks but is there any sign ofa the last few weeks but is there any sign of a final decision as to president zumas fate . Not yet but there will be. I wish i could tell you when. Theyve been talking for over six hours. Thats not unusual with the anc and especially the National Executive committee, which has 90 members and everyone is entitled to their say. They should reach a consensus and avoid a divisive vote. The scenario that has been sketched out is that they will agree to recall president zuma, in other words ask for his resignation and ina other words ask for his resignation and in a carefully choreographed move he will agreed to resign. It isnt confirmed or guaranteed. The doubt is moving onto the floor of parliament where you may have a vote of no confidence or impeachment which would see anc members voting against their own leader. Cyril ramaphosa once to have leadership and avoid a gift to the opposition. It is hoped they will reach a decision that will see president zuma, perhaps tomorrow morning, agreeing to resign.

Tourist flights to tunisia will resume tomorrow, two and half years after 30 british holidaymakers were killed in a terror attack at a beach resort in the coastal city of sousse. A travel ban later imposed by the uk was lifted last summer and now thomas cook will operate flights from manchester and birmingham. 0ur security correspondent Frank Gardner has travelled to tunisia to assess what security measures have been taken to reassure visitors. Tunis by night, and a National Guard unit prepares to raid a suspected terrorist hideout. Their commander tells us they know of 500 islamist extremists living in just three Square Kilometres here. Well, theyve just gone into a house here. We can hear some shouts. Were in a tiny little backstreet, and theyre looking for members of an isis cell that has been in libya, they suspect, so the whole street is flooded with these armed National Guard soldiers. Three years ago on this beach near sousse, an isis gunman shot dead 38 people, 30 of them british. Now, tunisia is getting training from royal navy instructors in maritime security, while met Police Detectives have been training up hotel staff. At four key airports, British Aviation experts have installed new screening equipment, so i asked britains ambassador, how safe is it now . Well, no country is 100 safe, as we saw with the tragic attacks in london and manchester last year, but it is safer here than it was in 2015 because the tunisians capability has improved. In the resort town of hammamet, where thomas cook is taking the first returning british tourists, i asked the Hotel Manager what precautions hes taking. We have around 60 cameras all around the hotel. The exterior cameras are all monitored 24 hours by people behind the screens. But tunisia sits in a dangerous neighbourhood. Across this border, libya is in chaos, and isis has bases. The manchester bomber trained in libya, and so did the sousse gunman. Back in the capital, tunis, the night raid yields results. Suspects were arrested and will now face trial. Tunisia has made huge progress against terrorism, but if its tourist industry is to recover fully, it will need to stay vigilant.

Liam is the best man and had organised it all. His friends last saw him at 1 30am in the reeperbahn area of the city. We knew that his phone battery had died on friday evening so we might not have just heard of him overnight.

Thats when we really knew something wasnt right. Some of liams family and friends have stayed in the city hoping to help trace him.

Kensington palace has released more details of prince harry and Meghan Markles wedding plans. The ceremony will take place at Windsor Castle on may 19th. 0ur royal correspondent Nicholas Witchell reports. Three months to go, and so much to do, but harry and megan are said to be involving themselves closely in details of the wedding arrangements. The venue we know will be the magnificent setting of st georges chapel inside Windsor Castle. Dating from the 15th century and rich in history, its here that the banners of the knights of the garter are displayed above the choir stalls. It will be the setting for a ceremony which will be very much more a family wedding than a state occasion. We now know the timetable for the day. At noon, the wedding ceremony will begin, well timed for american breakfast television. At 1pm, the carriage procession will begin. At around 2pm, there will be a wedding reception inside the castle. Then in the evening, there will be a private dinner and reception for the couple, theirfamilies, and close friends. In terms of the carriage procession, this is the route they will take. At 1pm, from Windsor Castle, they will go down castle hill and windsor high street, and then out to the south of windsor along kings road, before returning to the castle along the long walk. A processional route which Kensington Palace hopes will give people a chance to feel part of what they call, this special day. One problem which hasnt been resolved is whether prince william, the president of the football association, will be able to get to the fa cup final, which is due to kick off at wembley late that afternoon. It could be tricky. The problem would be getting william back to the castle in time for that family dinner in the evening. If the cup final went into extra time, hed have a problem. So windsor may well win the day over wembley. And at the centre of things at the big match in windsor will be these two, a bride and groom becoming, well, not exactly a mr and mrs, more probably a duke and duchess. Nicholas witchell, bbc news, windsor.

Commentator goodness me quite how no one was injured, especially slovakias klaudia medlova, almost defied belief. As one after another, their hopes crash landed. All of the 25 riders fell at some point, including britains aimee fuller. The wind forced her to pull out of a jump on herfirst run, which meant on the second it was all or nothing, and agonisingly it was the latter. Fuller finished 17th, but more importantly, intact. The conditions, she said, where simply brutal. It felt like i had a sailboat under my board. The wind ripped me sideways. There wasnt a chance i was going to land. So, yeah, devastated. Amidst the chaos, americas Jamie Anderson kept her balance and her 0lympic title. 0rganisers felt it had been safe to start the final, but was it . The coaches and judges, they all have a chat together and make a decision at the top of the slope. I wonder what went on in that conversation, why somebody didnt say, lets postpone this. These biting winds have already blown the schedule of course. Todays womens giant slalom had to be postponed, and with more high winds forecast tomorrow there could be more disruption.

The snow moving away from Northern Ireland but leaving thick cover over the higher ground. Through the rest of the davie provan that nation is slowly moving over east anglia and south east england so it will feel particularly cold. Sunny spells for the rest of us but it will be cold, temperatures struggling, four, 5 degrees. 0n temperatures struggling, four, 5 degrees. On tuesday night, icy stretches and then a weather system racing from the atlantic and it will do more of the same, strong wind, then a band of rain, turning to snow over the higher ground, leading to further significant accumulations. Some snow at lower levels in eastern scotla nd some snow at lower levels in eastern scotland but things will turn milder from the west with temperatures up to double figures late in the day.
