here on bbc news. good afternoon and welcome to bbc news. doctors say the nhs in england is likely to see its "winter crisis" extend into the summer because of continuing pressures on the system. figures analysed by the british medical association show that hospitals can expect similar problems with a&e attendances, waiting times and admissions reaching alarming numbers this summer. the government says it's planning to increase the funding to the nhs by £10 billion a year by 2020. richard lister reports. how does that feel? winter always puts hospitals under pressure. this was university hospital of north tees injanuary, one of many in england battling one of the most difficult winter seasons yet, with flu and norovirus forcing evermore people to seek treatment. but the british medical association says, without more money for the nhs

now, this winter overcrowding will roll into the summer too. the numbers of patients attending a&e, the numbers waiting more than four hours to be admitted, will be as great as the winter months, and we are likely to see trolley waiting times and pressures on beds similar to the winters of 2015 and 2016. looking at the past five years of data in england, there could be up to 6.2 million visits to a&e, resulting in more than 750,000 people having to wait more than four hours to be seen, and almost 150,000 spending that time on a hospital trolley. those waiting times are more than 5% higher than the government's official targets, and the bma says funding cuts over decades have resulted in insufficient doctors and hospital beds to meet demand.

the winter crisis, it warns, could be here to stay. the staff themselves seem to be working incredibly hard. the worry is that they are just running on empty, and it's... it's difficult to see how they are going to be able to keep going. i've got no complaints at the moment, but if i had a chronic health condition, i would be concerned about increased waiting times. it's no secret that demand for hospital care is growing. the government says it recognises that, too, and injected an extra £2.8 billion into nhs england last year, to be followed by another £10 billion in the budget from 2020. but the bma's concern that money may be too little, too late. the demands on the nhs in england are becoming overwhelming, it says, and it may no longer rely on the summer months to take the pressure off. richard lister, bbc news. alison saunders — the director of public prosecutions for england and wales —

is to step down from the role later this year, when her contract expires. her five years in charge have been marked by a series of controversies — most recently, the collapse of a number of high profile rape cases, where prosecutors had failed to disclose evidence to the defence. but alison saunders has defended her time in charge saying criticism is an "insult" to her 6000 staff in the crown prosecution service. here's our legal affairs correspondent, clive coleman. alison saunders, the head of the crown prosecution service, announced her departure, defiantly facing down criticism of her record. 0ur performance across the last five years has been as good as, if not improving, despite the cuts that we have taken over that period. and we have prosecutors up and down the country who come to work every day, who make really important decisions about people's lives, who do so professionally and well. dealt a tough hand, she inherited stringent cuts, losing hundreds of prosecutors

and other staff. but her time has been dogged by controversy. her decision that his dementia meant that it wasn't in the public interest to prosecute the late labour peer lord janner over allegations of sexual abuse was overturned. he was to face a limited trial of the facts before his death. well, sadly, she has been a very disappointing dpp. it's notjust my opinion, it's the opinion of the profession as a whole, and it stems from this central policy that all complainants are to be believed. they need to be sifted, they need to be considered. otherwise it will lead to the injustices that my family suffered. it was the collapse of a series of high—profile rape cases, like that of liam allen, because of failures by police and prosecutors to disclose critical evidence to the defence, that led to the most recent criticism. it prompted an urgent review of all rape and serious sexual assault cases. afterfive years heading up what some call the nation's law firm, alison saunders will leave

the crown prosecution service when it's under intense scrutiny. clive coleman, bbc news. some breaking news to bring you. within the last few minutes, confirmation that the former wife of nelson mandela, winnie mandela, has died. she was, of course, is that what in the fight shared by her husband against apartheid. she has died at the age of 81. she met nelson mandela in 1957, they married a year later and had two children together but, later in life, a controversial life, as her marriage ended to nelson mandela, and she went into politics. in 1991, she was convicted of kidnapping and being an a ccesso i’y convicted of kidnapping and being an accessory to assault of a young activist, who was called by egg

member of her bodyguards to a football club. —— a member. a six—year jail sentence was football club. —— a member. a six—yearjail sentence was reduced toa six—yearjail sentence was reduced to a fine and, a few years after nelson mandela's release, her marriage to him began to flounder. the news of her death has been confirmed by her pa. they divorced in1996, confirmed by her pa. they divorced in 1996, after 37 years of marriage. she has been an mp, but has not made many appearances in parliament in the last few years. in 2016, she was given an order during the national awards ceremony for her contribution to the fight for liberation of the people of south africa. she dies very much a controversial figure people of south africa. she dies very much a controversialfigure in south african history. that is the breaking news that winnie mandela

has died at home, and she was aged 81. we will bring you more on that throughout the afternoon. two men were killed on the m62 near bradford in the early hours of this morning after a crash involving a car driving the wrong way down the motorway. a 22—year—old man was arrested on suspicion of causing death by dangerous driving after failing a roadside breath test. britain's biggest teaching union has warned that growing levels of poverty are having a significant impact on children's learning. 0ne headteacher said some pupils are so malnourished they're "filling their pockets" with food from school canteens. the government says it is supporting initiatives such as breakfast clubs to help the most disadvantaged children. marc ashdown reports. "heartbreaking." that's how some teachers have described child poverty and how it's affecting their ability to learn. this snapshot survey of 900 heads, teachers, and support staff in england, wales, and northern ireland, found 87% think poverty is having a significant impact on learning. 60% believe the situation has

worsened since 2015. in their responses, teachers talk of children coming to class with pale faces, dirty clothes, and worn—out shoes. a growing number of schools say they're now setting up clothes banks and food banks to support struggling parents. heads say it's having a wider effect on school budgets, with teachers having to intervene to make sure children are getting the basics. one of the problems that we have now is the capacity of other agencies to support us as they used to is not there. we're becoming social workers. not "becoming," we are social workers. members of staff are becoming social workers. putting their hand in their own pocket to support children with christmas presents, with food, with uniforms, and that, in 2018, should not be happening. the department for education says it is continuing to support the most the country's most disadvantaged children through free school

meals, pupil premiums, and a new £26 million fund to launch of improve 1,700 breakfast clubs. marc ashdown, bbc news. china has imposed $3 billion worth of new import taxes on a series of us goods in response to president trump's decision to increase tariffs on imported steel and aluminium. beijing claimed the move was necessary to "safeguard" its interests. there are concerns that such actions could spark a global trade war as our correspondent in beijing, stephen mcdonnell, explains. for those who are concerned about an international trade war developing, i think it's fair to say that today is not a very positive day, because, as of now, there are 128 us products which have chinese tariffs on them. and here are some of the numbers... so, there are 120 products which have a 15% tariff on them, and another eight products with a 25% tariff. now, amongst those with a 25% tariff, we have scrap aluminium and pork.

and with a 15% tariff, nuts, fruit, ginseng and wine. but i should stress, this is only china's response to the first round of us tariffs. the trump administration has promised a second round. and of course, beijing will have to respond to that. this is why analysts are worried about a tit—for—tat escalation of tariffs which could blow up into a trade war which draws in other countries, especially those in europe and asia. i've been speaking to dr frankiskos filippaios from kent business school, who says neither country wants a full—blown trade war. what they're actually trying to do, is they're trying to, kind of, if i use the expression, sow their teeth at the moment. us, for example, when you see the tariffs on steel and aluminium, they're not targeting china. china is basically less than 1% of exports of steel and aluminium to the us, and if you look at the retaliation

that has come from china, yes, it includes a number of agricultural goods yesterday, but actually it excludes one of the major exports, which is soya beans. soya beans is close to 15 billion exports from the us to china, and the tariffs are now imposed on about, products of about three billion. so it's not hurting either country at the moment, but it is hurting consumers who buy these goods. it is, it is, of course, and if you look at the past actually, the case where last time the us administration tried to impose steel and aluminium tariffs, which was from the bush administration if i remember correctly, back in 2002, there was quite a substantial negative effect, and there are studies that have demonstrated that, to the us consumers. so in a trade war, effectively the consumer will definitely lose, the final consumer, because they will have to pay higher prices, and whether that is justifiable by the economic or political gains

is a lot of the time questionable. the us is increasingly exporting products like wine, how will that particular industry suffer with this? well, china is a market, but it's not the biggest market. it's one of the things that we would call an emerging market, in terms of wine. chinese consumers are getting accustomed to drinking wine. it might not have immediate impact, but it might have impact in the future, especially if the us producers consider china a strategic market for the future for them. it was no surprise the import tariffs on particularly steel because president trump has been talking about this for a long time, as indeed other countries have. is there a risk that this spreads globally? well, one of the things that is quite interesting at the moment is to see where the different countries will position themselves, so for example the aluminium and steel tariffs at the moment, the major exporters to united states is canada, and one of the things

that i have written about is that the us are trying to kind of push a political agenda there because the north american free trade agreement is up for negotiation. and the way the chinese have responded today, targeting particularly us products, but trying to avoid hurting exports from the european union orjapan, it looks like there is a very interesting game there, where either parties, either sides will try to get other countries clustering round them in that trade war. it is going to be very interesting to see what the next couple of moves, in terms of the two countries, in order to see who are going to be their allies in this potential trade war. but in the meantime, does the global economy, does it adjust, because if you can't get these goods or they're too expensive from one country you're going to look elsewhere? you can't adjust that quickly and that's the issue with international trade, you can'tjust change your

production overnight, from one location to another. you can'tjust change your distribution systems. yes, we have moved to a period where with the internet and intranet in companies, it's quicker, but it's actually not that easy. so what we might see in the short—term, we might see significantly higher prices for the final consumer, in some of those locations. i think we are going to see the political side of it developing as well. we will see whether the two countries might end up resolving their dispute through wto. the headlines on bbc news: winnie mandela — the south african anti—apartheid campaigner and wife of nelson mandela — has died at the age of 81. the nhs in england is likely to face a "year—round crisis" , as this winter's pressures extend

into the summer — that's the warning from some doctors. the director of public prosecutions, alison saunders, will stand down in october after a series of recent controversies. sport now and, for a full round—up, let's go to the bbc sport centre. good afternoon. we begin with some news emerging from west bromwich albion in the past hour, as the club confirmed manager alan pardew has left by mutual consent. it follows a run of eight successive league defeats for albion, which has left them seven points adrift at the bottom of the table. here is our sports reporter, simon stone. he's only been in the job five months and only won one premier league game. it's been an awful time in charge, an awful season for west brom, who had only won three premier league games. they sacked tony pulis

in november and they hope that alan pa rd ew in november and they hope that alan pardew would turn the season around. it hasn't happened and he has paid the price. they are ten points adrift at the bottom, with six games left. they have no chance of saving their premier league skins and i think they can't wait for it to end. now to the championship, where derby county ended their eight—game winless run with a 1—0 win over preston north end. preston had a chance to overtake derby into the play—off spots when they were awarded a penalty in the first half. in the second half, tom lawrence gave derby the lead. that was enough for the win. they are now up to fifth place. there are more than six championship games to tell you about today and we'll keep you updated. england will need to take all ten new zealand wickets on the final day of the second test if they are to avoid a series defeat. they began the fourth day in a strong position — both dawid malan and captain joe root scored 50, as england built a healthy lead.

root missed out on a hundred again, though, when he was dismissed by david wagner. he declared and set new zealand a daunting 382 to win. that looks unlikely but, afterjames vince dropped tom latham, they got through to the close without losing a wicket, finishing on 42 without loss. ronnie 0'sullivan is bidding for a record sixth ranking event title at the china open. currently on five for the the china open. currently on five forthe campaign, the china open. currently on five for the campaign, victory would see him surpassing both stephen hendry and mark selby. 0'sullivan hasn't beenin and mark selby. 0'sullivan hasn't been in this tournament since 2000, but there is more than the record to play for, with a top prize of £225,000. ian poulter admitted packing his bags to go home on friday, but bet he's glad he stuck around for the weekend. victory at the houston open earned him the final place at this week's masters. poulter was tied for 123rd after a below par first round, but he won a dramatic play—off last night against beau hossler to earn his first

stroke play victory in the united states, and a place at augusta. it doesn't just it doesn'tjust mean getting to augusta. there are bigger things on the horizon. the last couple of yea rs has the horizon. the last couple of years has been a long road, with injury, questioning whether i've got a pga tour card or not, and then having some form and not quite finishing off in the past so, to get my first stroke play victory, that's a big one. to get the exemption is big. to move up in the world ranking points is a big one. it bodes well for him. elsewhere, an extra day is needed to decide the winner of the first women's major of the season. korea's inbee park and sweden's pernilla lindberg couldn't be separated before darkness fell at the ana inspiration in california. the pair will start at the par four tenth at apm, with the tournament to be decided by a play—off for the second year in a row. there are six matches in rugby

league's super league today, five of them already under way. you can follow them on the bbc sport website. for now, that's all from us. an abandoned chinese space laboratory — which has been in orbit around the earth since 2011 — has broken up on re—entry over the south pacific ocean. tiangong—1 was being used to train astronauts, but it stopped functioning in 2016, meaning technicians on the ground weren't able to manage its controlled descent to earth. lebo diseko has more. heavenly palace blasting off. china's first space station was supposed to be a launch pad for bigger and better projects. but since then the eight tonne spacecraft around the size of a school bus has stopped working and come crashing down to earth. there was much speculation over where it might fall with estimates including south america, africa, the middle east, central asia to name just a few. in the end, the south pacific

is where it came down, most of it is said to have burned up on re—entry with any debris falling into the vast waters below. all this is a far cry from the space station's glory years when two different crews of astronauts visited. china says it's dealt with the situation according to international conventions but it all seems pretty embarrassing for the country's space programme. more than 7,500 tonnes of redundant space hardware is thought to be circling the earth. a uk—led research team is putting a satellite into orbit this evening to try to track the debris and catch it, as our science correspondent, jonathan amos, reports. it's getting extremely busy up in space. it's notjust the working satellites, but all the debris from past missions as well. more than 7,500 tonnes of redundant hardware are now thought to be circling earth. it's material that poses a collision hazard, with the danger

of creating even more debris. that's where this small european satellite comes in. known as "remove debris," it's been developed at the university of surrey. it'll demonstrate technologies that enable it to monitor, approach and ensnare junk. in one experiment, it'll eject an object and then throw a net around it. in another test, it'll fire a harpoon at a target to see how such projectiles behave in space. once these demonstrations are finished, the remove debris satellite will ensure it doesn't add to the problem by deploying a giant sail. this will drag in the upper atmosphere and pull the satellite rapidly down to earth. the remove debris spacecraft will be stored at the international space station for a few weeks before beginning its experiments in late may. jonathan amos, bbc news. joining me now from darmstadt is holger krag, head of space debris at the european space agency. thank you for your time. first of

all, can i talk about what has happened with the chinese debris that has crashed somewhere in the south pacific. how worried were you about that? we were not so worried, because these 8.5 tonnes of hardware, they just because these 8.5 tonnes of hardware, theyjust constitute 10% of what is re—entering anyway in a year so really every year we have 100 tonnes of space hardware re—entering, so it became quite normal, although the size of the space station has been exceptional, but it all went well. that's a relief, because the chinese had no control. it was their embarrassment, do you think, that they lost any ability to control the re—entry? all technical systems can fail. as i said, we have 100 tonnes of space hardware coming back in an uncontrolled way. the majority of

objects come back in an uncontrolled way, so having controlled re—entries into a safe spot like the south pacific is an exception. is it true that space debris, what goes up must come down, or is some of the stuff up come down, or is some of the stuff up there going to be doing so for but unless somebody does something about it? we are glad for everything that comes down safely, because the problem in space is even larger than the problem on ground. we have quite some accumulation of space debris. 20,000 objects can be tracked from the ground, and their position is precisely known. they are larger than the size of a football, and there are over 50,000 that are larger than a centimetre, and all of them are quite dangerous because of them are quite dangerous because of the high velocity they have when they impact on satellites. so we have a significant problem up there. 20,000 objects you have to avoid! added space travel wasn't risky

enough, you've got to keep your eyes open up there! that's right. there isa open up there! that's right. there is a fleet of 20 spacecraft, and every month we have to send one of oui’ every month we have to send one of our satellites on a collision avoidance manoeuvre, in order to prevent collision with one of these objects. we are looking at pictures of the university surrey expedition, launching tonight, to work out how best to collect debris. presumably thatis best to collect debris. presumably that is something you welcome? indeed, we have to look into this kind of technology, because it will become relevant in the future. we have to do two things. number one is to prevent additional debris. for that, we have to change a way we do space flight, meaning that we have to dispose of objects after the mission, so they don't spend too much time in orbit after the end of the mission. second, we have to do what this mission demonstrates, to look into technology that will help

us look into technology that will help us to remove debris. who is responsible for the debris, if it does come down and caused damage on earth? for space debris causing damage on earth, there is a clear convention. it's called the liability convention. it is connected to the state that has launched the object. that state will remain liable and even have to be liable for damages caused on ground. a lot of people will be staggered to hear that there is this amount of stuff going around the planet, and it is all useless and it does nothing, is that right? it does nothing, is that right? it does nothing, that's the definition of space debris, it doesn't fulfil any useful purpose any more. it is rather a risk to other missions. and, if this attempt by the university of surrey works, and they find a way to pinpoint the debris, catch it and bring it back to earth, who do you think should pay for that? that would be very hard to

find somebody paying for that, u nless find somebody paying for that, unless there is legislation that forces s pa ce unless there is legislation that forces space actors to clean up if they have left something behind. it is important to remember that it is much easier to keep space clean as long as you have your spacecraft under control, because then you can dispose of it by using its own means. 0nce dispose of it by using its own means. once the mission is off and contact is lost, it becomes very expensive, and you'd have to do such missions the way they are demonstrating now, actively removing objects, and that gets expensive, and nobody would do it unless legislation stipulates it. head of space debris at the european space agency, thank you for your time. no problem. one of the most senior leaders in north korea has reportedly made a rare apology to visiting south korean journalists prevented from covering sunday's k—pop concert in pyongyang. kim yong—chol said it was wrong to hinder the free media at the event, attended

by the north korean leader. the concert is the first in the city in over a decade and took place amid improving relations between the two countries. from seoul, laura bicker reports. these k—pop stars, called red velvet, are known for their raunchy routines. many wondered how this south korean style would go down in the north korean capital. but leader kim jong—un himself came to watch, welcoming the applause from the invited pyongyang elite as he took his seat. later, as the north korean leader posed for a photo with the group, he described the concert as "a gift". translation: the audience gave us a great response. they clapped a lot and they sang along at the end of the concert. they gave us a big hand even after we left the stage, so i was really touched. but usually being caught with any kind of foreign pop music in north korea is a crime.

and kimjong—un has been even tougher than his father. defectors have reported harsh jail sentences. the regime is very guarded about outside influences on its people. so, the more interaction and the more exposure that north korean people get to south koreans, who represent a much freer, richer, you know, more advanced and cosmopolitan culture than what exists inside north korea, the better. so, one concert is better than nothing. you know, ten concerts would be better than that. and the more the better, basically. this is a pressure point that we should be needling more when we're dealing with north korea. together, the south korean stars sang about a dream of unifying the two koreas divided by war. the hope of the government in seoul is that this kind of exchange will lead to lasting peace on the peninsula. and those taking part hope

for more in the future. translation: i think the role of an artist could be more important than that of a politician, who can be very formal. if unification does happen, what both countries can relate and share is culture. i think about how i can be a little help to that. the audience may be clapping along to the same beat of their neighbours for now, but the two countries have been at this point before. all agree it's a start. but affecting real change on the peninsula will require more than the occasional overture. laura bicker, bbc news, seoul.
