A Public Health emergency has been declared in delhi due to soaring levels of air pollution. Officials are blaming farmers in neighbouring states who are using fires to clear land. They saythe thick fog has turned the city into a gas chamber. From dehli, Pratiksha Ghildial reports. It is like a scene from a dystopian Science Fiction movie. For a third day in a row now, residents of delhi are inhaling the seasons worst toxic air. In some parts of the city, the levels of pm 2. 5, the tiny particles that can penetrate deep into our lungs, are peaking at more than 500 mcg per cubic metre. The World Health Organization recommends a maximum level of 25. Im in central delhi, just near the Main Business district, and with the iconic india gate behind me. But as you can see, it is barely visible, with a thick blanket of smog around it. It is daytime, but hardly any sunlight is able to percolate the thick layer of smog that shrouds the city. The government says it is doing what it can. It has banned construction activities and plans to limit the number of vehicles on delhis roads. But the main reason for the toxic air here is the burning of crop stubble by farmers in neighbouring states of haryana and punjab, and there seems to be no respite from that. In november last year, i was really ill. I wasnt wearing a mask and it was so polluted last year also, and i got really, really bad lungs. My doctor suggested me to wear a mask every day. Translation i didnt realise how bad it will get. Do we really want our kids to grow in such an environment . No one really cares. No one wants to improve the situation. Several studies say that the pollution in delhi is damaging Peoples Health at an alarming rate and causing premature deaths. It really is a Public Health emergency. The former texas congressman beto orourke has dropped out of the us president ial race. On social media, he said his campaign for the Democratic Party nomination didnt have the means to go forward but that hed work to ensure donald trump was defeated. This is a campaign that has prided itself on seeing things clearly and on speaking honestly and on acting decisively. We have to clearly see, at this point, that we do not have the means to pursue this campaign successfully. For more im joined by Chris Buckler in washington. A year ayearago, he a year ago, he was the star of democrat politics, he had that famous magazine cover, i was born to do this, and was down from there. So the mid term elections a year ago when he bought that senate seat in texas, he really seemed to make a mark and capture peoples attention inside the Democratic Party. It was somebody who actually quite a lot of Young Democrats firmly believed in but he struggled to replicate replicate that start power on the bigger National Stage and you mention that magazine cover. He basically launched his president ial bid with this front page cover of vanity fair magazine. It was intended to really put him in as a big base within this political race but the truth is, even he acknowledged that in some ways, it did backfire because it put a lot of kind of attention on him and it meant that he had to really live up to that and truthfully, in the democratic debates, he hasnt really managed to stand out. Among this very crowded field of Something Like 20 people all vying to become president ial candidate for the party. He has certainly been very strong on issues like Climate Change and gun control and as he announced that he was not going to go ahead with this race, we had some of those who have supported his campaign crying, they genuinely believe in him. I struggled to find his final polling numbers. Who, if anyone, benefits from his exit . |j polling numbers. Who, if anyone, benefits from his exit . I think truthfully, the reality is beto orourke s so far down the pecking order that there is not that much to give away because what we are starting to see is really for cans of candidates start to break away from the rest of the pack. Elizabeth warren, bernie sanders, Pete Buttigieg and joe biden. They will go from state to state to try and convince democrats that they will rival donald trump on the 2020 election. They are the ones who are starting to break away. When you ta ke starting to break away. When you take a look at the other candidates, single digit percentages and low digit percentages. You are starting to get an idea of who could potentially be and at the moment, Elizabeth Warren seems to be the frontrunner. The british Prime Minister has played down president trumps doubts that the us would be able to do a free trade deal with britain under the terms of the Brexit Agreement with the eu. Borisjohnson has also distanced himself from the prospect of an electoral pact with the brexit party. Hes been speaking to our political editor, laura kuennsberg. Are there any circumstances under which you might work with nigel farage . Well, first of all, it is a great brexit. Its a proper brexit. It delivers exactly what we wanted, what i wanted, when i campaigned in 2016 to come out of the european union. It takes back control of our money, our borders, our laws. It enables us to do proper, all singing, all dancing free trade deals. Now, the difficulty about doing deals with any other party is that any other party im afraid simply risks or voting for any other party simply risks putting Jeremy Corbyn into number ten. There are no circumstances under which you would work with nigel farage . I want to be very, very clear that voting for any other party than this government, this conservative government, this one nation conservative government, is basically tantamount to putting Jeremy Corbyn in. Your mutualfriend, the president of the united states, thinks you should work with nigel farage. Is he wrong . Well, look, im always, always grateful for advice from wherever it comes. And we have great relations, as you know, with the us and many, many other countries. So hes wrong about that. But im just telling you, laura, what i think about the way to do this. President trump has also said that your brexit deal means that you cant really do a good deal with the americans. Is he wrong about that as well . Theres one thing hes right about, which is that theres certainly no question of negotiating on the nhs. That is absolutely true, and hes right about that. But, on the technicalities of the deal, anybody who looks at it can see that the uk has full control, as one whole uk england, scotland, wales, Northern Ireland as one uk. So the president hasnt looked at it, then. He said you cant do it. You cant trade, we cant make a trade deal with the uk. So hes misunderstood it . Well, i dont wish to comment on what he may or may not have read. What im telling you is what everybody can see from the terms of the deal that we did. If we can get it over the line by with this election in the middle of january, then well have it done. Why would anybody believe you on that, when you have broken your promise already, where we should have been out of the eu yesterday . Now, youve failed on that. I bitterly regret that we havent come out, but on the other hand, people said we wouldnt be able to get a new deal at all. In your first speech in downing street, you stood outside there and said, the buck stops here. And now this has gone wrong, you took your deal away from parliament, like taking your bat and ball away from home, and now youre blaming them. Well, with great respect, laura, i dont think that parliament were. I think that mps were never going to deliver that deal on that timetable, and they werent going to. So why did you try, then . Notjust by 31 october. It was clear, from what they did, they wouldnt have done it by christmas. They wouldnt have done it by 31 january. Their strategy was to keep rope a doping the government and then pushing the deadline on beyond 31 january. It would have been totally miserable. Would you rule out expanding the use of the private sector britain has become the latest european country to halt fracking for oil and gas because of safety concerns. The government withdrew its support after a report by its oil and Gas Authority warned that it wasnt possible to predict the size or timing of any earthquakes that the process might trigger. France and germany have already banned onshore fracking and it has been controversial in the uk for some time. In one of the biggest global sporting events of the year england and south africa will take to the field injapan on saturday for the final of the rugby world cup. Tens of millions of people are expected to tune in. Our Sports Editor dan roan is in tokyo. Another tactical masterclass by eddiejones. It may be the eve of the world cup final, but englands head coach still found time to put some local schoolkids through their paces today. 0k earlier, it was his captain taking instructions, this the squads final Training Session before the biggest game of their lives. Its a good session, boys, its good work. Puts us in good stead for saturday, that. Owen farrells leadership has been crucial to his teams journey in japan. Theyve had much to celebrate during this campaign, but he told me the job is not yet complete. We know that we cantjust expect to do the same as last week and the same to happen. Weve got to figure out ways to put ourselves in the best place possible to perform. It is 16 years since one of the most cherished moments in english sporting history Jonny Wilkinsons extra time drop goal sealing victory over an australia side coached byjones, to win the world cup for the first and only time. Today, the hero of that triumph was helping englands kickers as they try to emulate the team of 2003, but he told me this current squad can handle the pressure. I see a difference in this team, to a degree, because or certainly from some of the players, because i dont think theyre like the way i was. I think theyre not reclusive, or very introverted in that respect. I think theyre going to deal with it in their own way. But englands opponents, south africa, also have great pedigree in this tournament, their iconic 1995 triumph on home soil uniting a nation. 2a years on, siya kolisi is the teams first black captain, a powerful symbol of a more representative team. I havent seen support like this for our team in a very long time, you know, since 2007. And its really special, and i dont think anyone outside south africa understands what this means to us. And ive seen it, ive seen bits of it. You know, i havent seen all of it yet, and i know tomorrows going to be more, more, more special for the country. Organisers have hailed asias first world cup a towering success, but for the thousands of england fans descending on japan, there is only one place to be tomorrow. Wed love to get tickets. Were going to try when we go to tokyo. Weve got time, we arrive early in the morning. Kick offs around 6 00pm, i think, local time, so hopefully we can get tickets. Weve had requests to find tickets, but theyre like gold dust. You wouldnt sell your tickets youve got . No way. How much do you need, how much do you want . Go on. Not a chance. If england do return home victorious, these are the kind of scenes that will greet them after a win that could change the players lives and reinvigorate the sport. And well have more from tokyo a little later. Stay with us on bbc news still to come 50 years and counting well tell you about the russian postwoman who just keeps going and going.

After the last couple of weeks of course the protests started two weeks ago, they we re protests started two weeks ago, they were more violent and more massive than we are seeing right now, after these two weeks, after if you reforms, after a cabinet shuffle from president pinera, what they are looking for a more profound reforms in chile. The most specific demands they are looking for is a new constitution. So at this moment we are seeing in santiago, but other cities throughout the country, people gathering in social gatherings, but also in marches, manifestations, discussions, debates, to talk about a possible new constitution and what this constitution would look like. Boris, to be governor, the constitution was written during the pinochet military government in the early 1980s, house symbol would be for the country to decide lets have a constitution . Thats very difficult to decide for the country. Because of course theres a lot of sectors within the government, within chile, and a lot of money in the system, lead people, who would not profit from a new constitution. They would love to see the current constitution continue. But of course you have such huge opposition in the country from social movements, from organisations, from opposition sectors who all oppose this constitution.

The apec summit with xi jinping and donald trump possibly signing a trade deal there, it would bea signing a trade deal there, it would be a major step for chile, chiles business, and of course the Climate Summit, the first big Climate Summit after paris. It would be the best opportunity for chile to show its full force and for president pinera to show himself as a world leader. For there is for him it has been tragic. Terrible to have to be forced to cancel these summits. Boris van der spek speaking to us from santiago. Thank you very much. The indigenous khoisan people of south africa have secured a deal to be paid a regular income from the sale of a herbal tea which they used for centuries before it became a commercial product. Future sales of rooibos tea, or whats sometimes called red bush, will generate thousands of dollars a year for the people. Rich preston has this report. South africas cedarburg wilderness. Home to this little red plant. A red plant which breaks in around 60 million a year and accounts for about 10 of the global herbal tea market. Now some of that money will go to the people who discovered it. This area, around three hours north of cape town, is the only area where rooibos is grown. The khoisan people we re rooibos is grown. The khoisan people were using it for centuries before it was commercialised under colonial rule.

This has huge ramifications for the indigenous world and also for other industries were many, many people can be brought under our agreement. So it is a world first. And think its really important for that reason. The deal should bring khoisan around 650,000 a year, but they say its notjust khoisan around 650,000 a year, but they say its not just about the money. While there are monetary benefits attached, this was very much a dignity issue and the recognition by the industry about khoisan are the knowledge holders to the uses of rooibos. Its first knowledge was very, very important. And that was really what the struggle was about.
