welcome to bbc news. theresa may has defended her leadership at the start of a three—day trade visit to china. she insisted to reporters that she wasn't a quitter, following days of criticism from within her own party. speaking in beijing, the prime ministerforecast a golden era in trade relations between the two countries, but admitted that her government had to do more to advance its domestic agenda. our political editor laura kuenssberg is travelling with the prime minister. even the most carefully planned entrance can go a touch awry. a bit of pushing and shoving — not the political kind, this time. asia's red—carpets, though, hardly provide a rest.

theresa may is here to do business, but the tories are trading in her future at home. she, envious perhaps of that kind of discipline, is trying, well, as she might say, to get on with the job. although i may be visiting in winter, i have had the warmest of welcomes, for which i am very grateful. but, to get things done, leaders have to be able to lead. the prime minister says she will fight on, but concedes something has to shift. prime minister, on the journey here, you acknowledged that you and your government have to do more to be convincing. what is it that you plan to do differently, and will you stand up to your critics? i think that there are many people in the united kingdom who want to ensure that they and their families can achieve the british dream, of ensuring that each generation has a better future than the past. and, yes, we do need to do more, and we do need to ensure that we are talking about what we have already achieved.

but her chinese counterpart provided cheer... dangling the prospect of a future trade deal after brexit, with the start of formal conversations to scope it out. she isn't a natural fan of chinese opera, perhaps, or the diplomatic schmooze. there were some tricky moments today. conversations turned to human rights, north korea, and the brute force of china's steel industry. but these are very excited students could be joined by many others. deals for universities, exchange programmes, and others were announced. have a nice stay in china. thank you, thank you, well done to you. nice to see you! and this group used their high—tech skills to make a model of number ten, helpfully pointing out it had an emergency button, if ever there was a need for a swift escape. and there is an emergency button.

if you have an emergency, put there, and call the police. right, very good. the prime minister made very deliberate stops here, though, one to the banks of the yangtze river, to share her party's new—found focus on all things green. and she hopes by the end of the week to have guaranteed british beef is on its way back to china's tables, after 20 years, and there will have been handshakes on at least £9 billion of deals. china and britain not best friends, perhaps, but serious colleagues. this place reeks of power — a commodity theresa may has been grappling to hold onto in recent days. it is clear the prime minister is in no mood to quit, but she does seem to acknowledge she has to up her game at home, and abroad, to be sure of staying on. the historic bling, the flags, the ceremony — delicately choreographed, but easily dismantled. the prime minister travels

with the trappings of office. but she is vulnerable, not accompanied by reliable long—term support from her own side. our political editor laura kuenssberg, reporting on the prime minister's trip to china. the police and the crown prosecution service have been heavily criticised for the second time in a week, after the collapse of a trial. this one concerned people trafficking. one of the women accused of being involved had been locked up in custody for more than a year, and had even given birth in prison. the trial collapsed when thousands of mobile phone messages, that were disclosed late, cast doubt on the case. it comes after a number of rape cases were also abandoned because of disclosure issues. clive coleman reports. i was scared, i was in shock... cristina bosoanca's story shows the

devastating effect that this doormat failure to disclose evidence can have. after 13 tough months in prison, she can finally relax with the son she bore there. because they we re the son she bore there. because they were bullying me, was difficult when i saw them going to the visits. the prosecution case was based on the evidence of a female complainant who claimed cristina traffic her into the country to work as a prostitute. the complainant also alleged she was raped by a client and became pregnant as a result. while in prison, cristina ‘s lawyers repeatedly told the police that they we re repeatedly told the police that they were phone messages that undermined the wall and's story. at the beginning, i asked for my phone, i asked for the pictures. i asked for everything. —— woman's story. but they was, like, we don't care. everything. —— woman's story. but they was, like, we don't carem was only on the second day of the trial that 65,000 phone messages

we re trial that 65,000 phone messages were disclosed to cristina ‘steam. they fundamentally undermined the complainant's they fundamentally undermined the complaina nt‘s account. medical evidence served late also proved a woman was pregnant before coming to the uk. the case collapsed on friday, thejudge the uk. the case collapsed on friday, the judge demanding the uk. the case collapsed on friday, thejudge demanding police and prosecutors come to court today to explain. in court, his honour, judge perrins said there had been a wholesale failure of disclosure and serious and repeated errors by both the police and the crown prosecution service. under oath, a senior crown prosecutor apologised, said a full review was taking place, and that a report will be sent to the director of public prosecutions. this is not an isolated case, and whatever the findings are in this case, they are symptomatic of a problem that has been developing over the last 6—8 yea rs. been developing over the last 6—8 years. the government brought in a series of cuts which have resulted in underfunding and under resourced in the metropolitan police, for the cps and the criminaljustice system

asa cps and the criminaljustice system as a whole. what do you think of british justice, having as a whole. what do you think of britishjustice, having been through the process that you have been through? i really don't know. i don't want to say something rude. if they think somebody needs to be punished for something, they need to be sure. cristina 's experience shows disclosure failures go beyond recent highly publicised rape cases. there are likely to be more examples, each one affecting the lives of those charged, and their families. shares in the outsourcing company capita have fallen dramatically, after it warned that profits for the coming year will be much lower than previously forecast. the company has outlined plans for a major overhaul of its business, and suspended plans to pay dividends to shareholders. the journalist carrie gracie, who resigned as the bbc‘s china editor in protest at unequal pay, has accused the corporation

of having an illegal pay culture. appearing before the commons culture committee this afternoon, she said the bbc‘s response to her grievance that she was paid less than her male counterparts had been an insult. the director general, lord hall, who also appeared, said it was wrong that she had been underpaid. 0ur media editor amol rajan reports. a united front — several of the most high—profile female presenters on bbc news were in westminster today to support their colleague carrie gracie. reporter: do the bbc need to do more on equal pay for women? that's why we're here to support carrie. thank you. i was appointed china editor in... she resigned her post as china editor in protest at unequal pay. in blistering testimony to a select committee of mps, she accused the bbc of institutionalised discrimination,

when it had paid her less than other international editors. we knew there was inequality. we didn't know the details, because the bbc is extremely secretive on pay, but we knew we were underpaid. and i was determined, at this point, when i knew i'd give the china job every last ounce of my skill and stamina, i knew i would do that job at least as well as any man. the corporation's dealing with her grievance was, she said, insultingly shambolic, and she added that she would be declining nearly £100,000 in back pay. i have said i don't want that money. that's not what it's about for me. i feel my salary‘s a good salary, its public money, i... that's not what it was about. they're still not giving me a quality. and, in a concerted attack against bbc management, she said that for years it had created a fortress to keep out ordinary staff. i was so distraught by what had happened. anyway... then i thought, "no,

i have to fight." gracie's grilling went on for 2.5 hours. when said management emerged in the afternoon, the director—general apologised for the situation. i'm sorry it went to a grievance, and i said upfront at the beginning i'd very much like to resolve the case of carrie gracie with her. and i'm sorry this has taken so long, and i'm sorry we're in this position, yes. he went on to explain for the first time in public why the bbc believe there is a hierarchy of roles among correspondents. the idea that every single editor, home and abroad, i would imagine, should be paid exactly the same, i don't agree with. it should not be a matter of gender, completely agree. outrageous if it was. but, you know, you have balances between different editors, and we need to be very upfront about what that, as it were, pecking order is. there are two parallel conversations happening today.

carrie gracie spoke powerfully about the wider implications of her own case, and also the accumulated failures of the past. but the bbc management wanted to focus on the future. they want to shift this story from the injustices faced by carrie gracie to their new framework for greater transparency. the trouble is, many staff here have other ideas. the bbc has a clear plan, and is largely ahead of the industry on gender inequality. but carrie gracie's case remains far from resolved, or unique. amol rajan, bbc news. a prisoner has been stabbed to death at wormwood scrubs jail in west london. scotland yard said the victim, who is yet to be identified, was found with a number of knife wounds this afternoon, and pronounced dead at the scene. no arrests have been made. the man accused of crashing a van into muslim worshippers outside a mosque in north london has said the driver was not caught on cctv because he is an illusionist. darren osborne, who is a8, denies murder and attempted murder, saying a man called dave was driving. he told woolwich crown court he could not explain why that man was never seen, arguing that perhaps he could make himself vanish. mps have voted to leave the palace

of westminster while a proposed multibillion—pound refurbishment of the historic building takes place. the commons approved the motion by a narrow majority. the planned move won't take effect until 2025 at the earliest, and is part of proposed modernisation works costing £5.6 billion. a rare lunar event being called the super—blue—blood—moon has bewitched sky—watchers around the world. it can only happen when there is a second full moon in the same month, and when it is closest to the earth in orbit, making it look much brighter and bigger. and that has coincided with a lunar eclipse, which has given it a reddish glow in some parts of the world — something that has not happened for a generation. now it is time for newsnight, with evan davies.

he might have thought out sourcing public services did not work for the taxpayer, but another profit warning shows it may be doesn't work for private companies either. capita says it needs to streamline its business and get it debt down, the latest in a spate of knocks to the whole outsourcing industry. we'll take a long, hard look at when outsourcing helps and when it should be avoided. after decades of horrific violence in afghanistan, the international criminal court is considering a war crimes investigation. but could justice, much like peace, prove elusive in this war—torn country? they don't want what is sometimes called low hanging fruit, basically, that the foot soldiers who carry out but don't direct the nasty activities. you have to do apprehend

those people, and that is not so straightforward. and should we acquire exquisite consent before six? we will speak to a barrister about what consent is, and how best to get it. hello there. has outsourcing had its day? for decades now, it has been a mantra within government, that virtually any activity is best put out to the market — running trains, prisons, construction projects, anything. for a long time, some have thought that the private contractors coin it in, at the expense of the workers, and the taxpayers. but the news that a huge private contractor, capita, has had to make a profit warning, and has seen its share price plummet today, weeks after carillion went bust, raises the question — does sub—contracting work for anybody at all? capita is in a different place to carillion, it is taking action that carillion didn't, to prevent itself becoming another sad business casualty, but its problems are just
