Moment. Conservative mps are warned of severe consequences if they fail to vote with the government this week, including being barred as party candidates. As parliament returns, opponents of a no deal brexit hope to push through legislation within days, but a senior minister suggests the government may not be bound by it. Lets see what the legislation says. Youre asking me about a pig in a poke and i will wait to see what legislation the opposition will try to bring forward. Well be exploring the rift between downing street and some tory mps, and asking if it will lead to an election. Also tonight chaos at hong kong airport as action by protesters causes disruption and cancelled flights. 80 years after germany attacked poland, the invasion that sparked World War Two is remembered. The devastating environmental and human cost of demand for palm oil in the beauty industry. Just out of my make up bag, foundation, moisturiser, lip gloss. Palm oils in all these things and thousands of others. And the painters putting coastal erosion in the frame at lands end. Good evening. Conservative mps have been warned that if they fail to support the government in what is shaping up to be a crucial week for brexit, they will no longer be regarded as representing the party and face being barred as candidates at the next election. It comes as opponents of a no deal brexit prepare to try and push through a law that would prevent it. A cabinet minister has refused to say if the government would be bound by the will of mps, even if their effort results in new legislation. Heres our Political Correspondent iain watson. Chanting Boris Johnsons got to go a week of protests on the streets, and a week of rebellion at westminster lies ahead. Save our democracy these protesters want the suspension of Parliament Later this month lifted. But mps will still meet this week and opposition parties plan to seize control of the parliamentary agenda and pass a law effectively ruling out a no deal brexit. But if that happens, this cabinet minister refused repeatedly to say that the government would accept the will of parliament. We will see what the legislation says when it is put forward. Lets see what the legislation says. Youre asking me about a pig in a poke. Lets see what the legislation is. But michael gove also expressed hope that the government would defeat attempts to block no deal. I believe that a majority of mps in the house of commons this week will back the Prime Minister because we know the Prime Minister is making progress with our european friends and allies in attempting to secure a deal. And this could be the reason for Michael Goves confidence. A procession of government whips going into chequers, the Prime Ministers country pile. Over lunch, they cooked up a plan to turn up the heat on borisjohnsons critics. Tonight, the gloves are off, notjust in the battle between Boris Johnson and the opposition, but between the Prime Minister and conservative rebels, some of them recently cabinet ministers. Government whips, those responsible for party discipline, are tonight ringing around those rebels and delivering a blunt message if you vote with the opposition to block no deal, youll be blocked as a candidate for the conservative party at the next general election. Some of them perhaps didnt realise thats what borisjohnson meant when he said hed unify the party behind him. A meeting scheduled for tomorrow between the Prime Minister and the so called gaukeward squad, david gauke and otherformer ministers opposed to no deal, was abruptly cancelled tonight. Number ten cited a diary clash. But david gauke signalled he is likely to rebel. Sometimes there is a point where it is, you have tojudge between your own personal interests and the National Interest, and the National Interest has to come first. But i hope it doesnt come to that, and i hope that cooler and calmer heads will look at this and think that trying to split the conservative party in this way is not a sensible way forward. Labour say borisjohnson could defuse any row with parliament, if he puts forward his own brexit plan and gives mps a say. The Prime Minister can cut through this very easily this week by saying, im going to put my proposal up for a vote, and im going to live by the result. If Parliament Gives me backing to leave without a deal, so be it, and if they dont, ill abide by it. But he wont do it. Importing goods from the eu. This week, the governments going to step up its campaign to get us ready for brexit, but its clear some of borisjohnsons mps are far from ready for no deal. Iain watson is here. What do you make of the tough line downing street is taking and its likely effect . I think actually, most of the battalions are massing behind Boris Johnson at the moment. Nonetheless, there is still the prospect of a conservative civil war after this rather uncivil warning to mps that they either get behind borisjohnson oi they either get behind borisjohnson or they could be sacked as a conservative mp. How is that playing with the potential rebels . Some of them are immune to strong arm tactics by the whips because they are big figures like ken clarke and oliver letwin, they have said they will stand down at the next election in any case. Others who were due to meet the Prime Minister tomorrow and have had the Meeting Cancelled are angry about that because they say it is discourteous and their views are becoming even more entrenched. We also must remember that Boris Johnson has a majority of one, even with the help of Northern Irelands dup. If he sacks his brexit rebels, he would be presiding over a minority government which i think means the prospect of a general election, an early general election, coming ever closer. Interestingly tonight, a veteran conservative mp said to me he felt the real reason the rebels were being dealt with in this way was because if there is an early election in october, you couldnt have high profile figures like Philip Hammond standing on an anti no deal platform, so they are being told to either shut up or get out. Iain watson, thank you. Thousands of pro democracy protesters have brought chaos to Hong Kong International airport for the second time in three weeks, blocking the access road and sabotaging the rail link. It meant dozens of flights had to be cancelled or delayed at one of the worlds busiest transport hubs. Demonstrators first took to the streets of hong kong three months ago, demanding an end to plans to allow people to be extradited to face trial in mainland china. Since then, huge numbers have joined the protests, calling also for free elections and for charges to be dropped against protesters. From hong kong, heres our china correspondentjohn sudworth. Hong kong airport, a vital part of an open, free trading economy, under siege. Chanting fight for freedom with pilots having to clamber over the barriers. As the Pro Democracy Campaign tries to hit this city where it hurts. Well, this is the main airport approach road and, once again, this meandering, leaderless protest movement is showing its ability to take its message to the international community. They come, they disrupt, and, if necessary, melt away and there is very little the authorities can do about it. Thousands turned up for the action, and although many flights were still getting away. With transport links brought to a standstill, passengers faced major problems. Do you support what theyre doing . I support what theyre doing but theres means and ways of doing it. I dont think this is the right way. Hong kongs never had democracy and its certainly not going to have it in the future, so. What do you make of the disruption . Its bleep. Im trying to go on my honeymoon. Eventually, the Police Arrived in force, but, as predicted, the protesters had already vanished. Moving on to this nearby metro station, the service now a target of violence and vandalism for closing stations, giving protesters fewer ways to escape. Yesterday, similar acts were met by a fierce response, heavily criticised over accusations that innocent bystanders were caught up in it. But defended today in this police press conference. Minimum force was used, they said. It was anger over that incident, though, that helped fuel todays demonstration, with many walking home along the airport expressway, as this citys extraordinary, escalating cycle of chaos continued late into the night. John sudworth, bbc news, hong kong. Hurricane dorian has made landfall in the north west bahamas with winds of up to 180mph. The storm is the strongest hurricane in modern records in the region and residents of grand bahama, which is along its predicted path, have been evacuated. Officials are warning that a storm surge could be as high as 23ft. Also projected to be in the path of the hurricane are parts of the florida coast, and our correspondent Aleem Maqbool joins us now from palm beach. What are they expecting there . Well, it is relatively calm here still in florida, but we are, as you rightly say, on the projected path of this hurricane in the next couple of days, which is why many people have already boarded up their properties and moved away. But the problem for people here in the united states, as has been a case in the bahamas, is that this storm has changed strength and direction so dramatically in the couple of days, that it is so difficult to know where to evacuate and wear is going to be safe. The immediate concern, though, is for loss of life in the bahamas. Some of those storm surges that you were talking about are higher than large parts of the islands themselves. Then the worry is that the storm barrelled into florida and potentially then moves right up the east coast of the united states, through georgia, potentially devastating parts of South Carolina and North Carolina as well. That is for the future, though. Right now, a lot of people are holding their breath until we can properly assess the damage that has been caused to some of those population centres on the bahamas. Aleem maqbool in florida, thank you. The death toll from another mass shooting in texas has risen to seven. 22 others were injured, including a toddler, in a rampage that began with a Police Officer shot during a routine traffic stop. Shoppers were then evacuated from a mall as the gunman, identified as a 36 year old local man, continued to shoot motorists and passers by at random. He was shot dead by police. The german president , frank walter steinmeier, has asked for polands forgiveness at an event marking the 80th anniversary of the invasion that sparked the second world war. He was speaking in the polish town of wielun, which was the first to suffer german aerial bombardment. Our berlin correspondent, jenny hill, reports from warsaw. Sudden, violent, the attacks came from air, land and sea. 80 years ago, nazi troops stormed in to occupy poland, an act of aggression which triggered the deadliest conflict in human history. Air raid siren. Before dawn this morning, sirens to commemorate the first civilian casualties of the second world war. German bombers destroyed the town of weilun. Speaking in polish, the german president said he was sorry. Translation i bow my head before the victims of the attack on weilun. I bow my head before the polish victims of germanys tyranny, and i ask for forgiveness. In warsaw, a chance to reflect on the horrors of conflict past, but among the leaders and heads of state, two notable absences. Donald trump cancelled his attendance at short notice, and the russian leader, vladimir putin, wasnt invited. The leaders who came here today came to commemorate notjust war but europes hard won peace, yet they themselves are deeply divided over the very values on which post war europe is built. There was a sense at times today that the unity those leaders are supposed to represent is in fact rather fragile. Jenny hill, bbc news, warsaw. Demand for palm oil in Food Products around the world has fuelled the destruction of rainforests in indonesia and borneo, as palms are planted on cleared land. What is less known is immense demand for palm oil from the skincare and beauty industry. It is used in more than two thirds of makeup products. Our environment correspondent Claire Marshall has been to Papua New Guinea to investigate the cost of a controversial industry and to see how palm oil can be sustainably produced. What helps to make lips glossy . Face cream creamy . Palm oil, a driver of rainforest destruction and in 70 of make up. And just relax your lip. Open. Emmy owns her own salon in somerset. We went with her to the other side of the world to investigate whats in the products she uses. This is one of the largest Palm Oil Plantations in Papua New Guinea. To make way for it, the forest has been cut down, huge chunks at a time. Nobody sees this. We dont appreciate kind of what goes into. Putting things on our face or what we use to, like, wash with. This side of it should be shown more. We came uninvited and this is what we found. There were young children, barefoot, working in the searing heat. Do they have any rules saying no children or. . There is no rules for children or anything. They have to bring children. They have to work in the farm so they will have money. In a nearby village, more children of the plantation. Some clearly need medical help. They say, when the Palm Oil Company came, it promised them a new hospital. Eight years later, its still not been built. We used to live by the forest. The forest was our source of food. It was just like our supermarket. But now the company came, we lost everything. In another village, they tell us a similar story. Bhiwani Oil Palm Plantation is not a certified sustainable Palm Oil Company. It told us it acted legally, it didnt allow child labour and said the area had been neglected for decades. It had broughtjobs and benefits and was committed to addressing the needs of the villagers. Its important to remember that this whole process, its impact on the forest, the communities, its all down to produce a product that we want. This is just out of my make up bag, foundation, moisturiser, lip gloss. Palm oils in all these things and thousands of others. We went to a different part of Papua New Guinea to see a company that has signed up to produce palm oil in a better way. On this certified sustainable plantation, they follow strict rules. They plant and harvest the palms but dont cut down any new rainforest. They also pledge to treat workers fairly. I feel happy. The Company Provides water. Yeah. And, like, transport for the children to go to school. The fruit is taken off to the mill and processed. This oil gets a stamp, a bit like a fairtrade one, but most of the time, this isnt put on product labels. The average consumer going into the supermarket, you know, doesnt know. All they know at the moment is that palm oil is bad, and thats particularly frustrating for the Sustainable Palm Oil industry. Emmy glimpses a fragment of rainforest not yet destroyed by palm. Its incredible im going to go home and try and look into the brands that i use, to make sure that the ingredients that are in it, you know, where its come from. Palm oil is up to ten times more productive than other Vegetable Oil crops. Producers hope the sustainable, or acceptable side, more acceptable side, wont stay so hidden. Claire marshall, bbc news, Papua New Guinea. And theres more on Palm Oil Production in bbc threes unmasked make ups big secret, which will be on the bbc iplayer from tomorrow. Formula i paid tribute to Anthoine Hubert today, the french driver who was killed in a crash in formula 2 at the spa circuit yesterday. At the belgian grand prix, ferrari secured their first victory of the season, as Patrick Gearey reports. For a minute, the engines fell silent. Spa paused for Anthoine Hubert, killed in a crash in the formula 2 race here just yesterday. He was only 22. A tragic reminder of the risks drivers face as an occupational hazard. And its lights out and away we go. At these speeds, anything can happen. Many of the crowd had come to watch max verstappen, born in belgium, and yet his race was over within a lap. Most importantly, he was unharmed. Meanwhile, Lewis Hamilton was chasing the two ferraris, a test of strategy and velocity. Hamilton took longer in the pits than he might have but in his mercedes, he knows he can make up time. He passed a flagging Sebastian Vettel into second and went after charles leclerc, but the man from monaco had extra motivation to win his first grand prix. Hed raced with his friend Anthoine Hubert for many years. Radio this one is for anthoine. Difficult to enjoy a weekend like this. For leclerc, some achievement but one of the moments of his life had been put in a sober context. Some things are more important. Patrick gearey, bbc news. In tennis, Johanna Konta is through to the quarterfinals of the us open after beating number three seed karolina pliskova. Konta recovered from a set down to win 6 7,
