this is bbc news, the headlines: borisjohnson has resigned as conservative party leader, saying he will stay on as caretaker prime minister until the autumn. but pressure is mounting for him to step down completely as soon as possible. in his resignation speech, mrjohnson blamed his colleagues for what he called a herd movement. attention now turns to who might replace borisjohnson, as the list of potential candidates grows by the hour. defence secretary ben wallace appears to be the favourite among tory party members, ahead of penny mordaunt and rishi sunak, the former chancellor of the exchequer. foreign ministers from the 620 are meeting in bali to discuss the disruption to global food and energy supplies caused by russia's invasion of ukraine. joining the us secretary of state, antony blinken, are russia's top diplomat, sergey lavrov, and the chinese

foreign minister, wang yi. now on bbc news, our world. china is cracking down on hong kong. it's 25 years since britain handed back control of the city to china. back then, promises were made to protect fundamental freedoms. now, beijing is tightening its grip on those who dare to speak out.

we've spent time with those who will not be silenced. if we stay here, we will be brainwashed. as record numbers leave hong kong, what will life be like for those that remain? i have been reporting from hong kong since 2017 but in the last two years i have witnessed first—hand the dramatic transformation of the city.

music. this isjennifer, one of thousands who once protested against the government. arrested with a0 others in 2019, she is now preparing for prison life. i don't smoke. ijust heard that in jail you can use these cigarettes as, like, currency, so i got a pack of these. and i'm trying to see if, if i can use these as money injail but... i am still not sure about that. jennifer maintains she was a peaceful protester, but she has been convicted of rioting. now she is facing up to ten years in prison.

i sincerely take it as a challenge for me. it is like... in everyone�*s life you definitely have some trouble that you have to overcome. she is allowed to write to the judge to ask for leniency. what are you saying to the judge? i am telling him about my own story. like, my personal background.

in 2019, kin was a 18—year—old student. after a violent confrontation, he became the first protester to be shot by the police. the dramatic moment was captured by student journalists. police say they were acting in self—defence. released from hospital, kin was charged with rioting and assaulting a police officer.

weeks after we met, kin attempts to flee. he is seeking asylum in the us consulate. i catch the moment on my phone. sorry, sorry, sorry, sir! no photos here! they turn him away, and i won't see him again for some time.

it's june 2020. after months of unrest, beijing imposes a wide—ranging national security law in hong kong. while covering the crackdown, i also get stopped by the police. i am a journalist! the new law silences the protest movement. anyone found guilty of violating it, can be imprisoned for life. every country and territory needs national security law to protect itself. we must protect our people from espionage, terrorism, political interference, subversion. that is what every government does. almost every international government would say this is a draconian law. why do they say that? because they are biased. because they have an

ideological bias against china and hong kong is part of china. at least it's better thanjail in china. in hong kong, my family can know what happens to me. 24—year—old jennifer is getting ready to go back to court. convicted of rioting, she is coming to the end of a 2.5 year process. she is saying goodbye to herfamily. they have asked not to be filmed.

it has been a long way and finally we can go closer to the end of this trouble. scores of other young people were outside court today, many awaiting sentencing for similar charges. some of their supporters wear symbols of the protest movement. jennifer gets 3.5 years in prison. she is one of dozens sentenced today and taken to jail. in the last three years, more than 10,000 people have been arrested as part of the crackdown.

nearly 3000 of them have been prosecuted and around 1200 sent to prison. ronson chan is one of the best—known journalists in hong kong. ronson has been reporting from the front line since the protests began. it's made him a target.

this is one of the last independent news outlets left in hong kong. a website called stand news. yin pong lam is an editor here. he is determined to continue reporting, come what may. we can be described as one of the most influential media outlets in what you call the pro—democracy camp. we do not describe ourselves like this, but maybe to the authorities, they see it this way. someday they will come to your door, and i think we would probably be an obvious target to them.

stand news survives, for now, but as chairman of the journalist union, ronson fears he's becoming an even bigger target. he tells me his wife is worried about his safety. i'm back in touch with kin, who was shot by the police. he's still facing serious charges. it's been several weeks since i saw him being turned away by the us consulate. he's in bad shape.

he's worried about being sent to prison. the uncertainty of the new law has spread fear across this city. when i leave, kin doesn't tell me what his plans are, and it's best i don't know.

this one is all the art materials, because i like doing artwork with him. tomorrow, the home will be empty. eddie and mason are part of a mass exodus from hong kong. last year, the uk government offered the right to citizenship to residents born in the territory before 1997. it angered beijing, but tens of thousands have taken up the offer. the situation changed quite rapidly. many things are different. frankly, i don't feel comfortable to speak freely, and i'm a bit worried about my children.

even though they're leaving, eddie's wife, mason, has asked us not to show her face. she's a teacher and is worried about the government restricting what she can say in the classroom. we received many notices what we need to teach, what we can teach, what we can't say, because if we say something, they want — they didn't want to listen, then we may lose ourjob. if we stay here, then we would be brainwashed. i don't want my students and also my children to have this kind of education, because we have the right to know the truth. her husband eddie is an executive at a games company. they're giving up their comfortable life in hong kong for a new one in a country they've never visited. why do you think so many hong kong residents are leaving the city? i think they are pretty disappointed to the —

what happens in hong kong. they leave hong kong, their future uncertain. more than 1% of the population, 90,000 people, have left the city since the national security law was introduced. it's the legislative council election. the winners will decide the future of hong kong. pong has been assigned to cover it for stand news. my duty is to tell the public what really is going on right now in this so—called election. and, at the same time, to avoid being accused of breaking the law.

in the last year, almost all pro—democracy council members have been arrested or have fled the city. china has completely overhauled the electoral system here. now, only candidates approved by the authorities can stand, so—called �*patriots�*. junius ho is a beijing loyalist, standing for re—election. everybody is pro—beijing. everybody is pro—establishment. this isn't a real diversity of opinion. i...i beg to disagree. for those who run the show or participate in an election must be patriotic and love your country. would you expect some traitor to be your leader? most of them know they will win the so—called election

before the result is announced. 1,192 votes. but everybody pretends like they are running a competitive election, so it's really quite surreal. ten days after the election, national security police arrive at ronson chan's home in the early hours. ronson, the stand news journalist, livestreams it from his phone. ronson is taken away.

at the same time, the stand news office is being raided. six senior members of staff are charged with publishing seditious materials, but it's not clear what evidence the police have against them. pong is one of the few editors who isn't arrested. their assets seized, stand news is forced to close. their website is taken offline that night. the heavy—handed tactics work. i won't comment anything right now, 0k? after a day of questioning,

ronson is released without charge. these are the bad apples who are abusing their position. anybody who attempts to make use of media work as a tool to pursue their political purpose or other interests contravenes the law, particularly offences that endanger national security. they are the evil elements that damage press freedom. the next morning, i visit ronson at his apartment. deputy leaderjohn lee is now going for the top job. it's the election for hong kong's chief executive. after leading the crackdown on the protests, he's been hand—picked by beijing and he's the only candidate.

i hereby declare that the only candidate, mrjohn lee ka—chiu, is returned. congratulations. applause it's the anniversary of the tiananmen square crackdown, and pong is covering the event as an independentjournalist. in 1989, hundreds, possibly thousands died when soldiers fired on pro—democracy protesters in the capital, beijing. gunfire every year in hong kong's victoria park, tens of thousands hold a candlelight vigil to remember the dead. this year, the organisers have been arrested and the police are threatening to detain anyone who attends. they're out in force. if you ever wanted

to understand how much hong kong has changed, it's this. plainclothes police officers confiscating candles lit in remembrance. but hong kong refuses to forget. victoria park was once a place where the dead of tiananmen could be remembered. not anymore.

25 years since the handover, hong kong is becoming like any other chinese city. the promises of its special status broken. this is more than a crackdown. this is a transformation.

hello, there. it's going to be a lot of talk about heat in the next three and half minutes and we will get this out of the way quite quickly. rainfall. across a large part of the uk the next ten days. there is time although still not a huge amount, especially towards western parts of scotland, moving a little into northern ireland at times, because we have high pressure to the rest of us, and a familiar story this week has been around that area of high pressure there are some weather fronts a time bringing you the chance of a little rain, especially the further north through parts of western scotland and northern ireland, a few spots of light rain and drizzle, not amounting to very much. sunny spells in eastern scotland where it won't be quite as warm as it was on

thursday. through much of wales and england though, a lot of sunshine, more so than on thursday and higher temperatures, near30 thursday and higher temperatures, near 30 the hottest parts of east anglia, above particularly the south—east of england. as we go into the weekend, this area of high pressure will gradually move across the uk, so more and more particularly across the northern half of the uk will fall under the influence of that, deflecting the better chance of rain even further northwards. still some cloud in northern and western parts of scotland, temperatures close to average for the time of year, and maybe a little bit cooler through parts of wales and england, although there will be quite a bit of sunshine around. that trend reverses no on sunday as we see high pressure moving in across us, and that means the warmth will build more widely, and that is helped by a more generous amount of sunshine even in scotland and northern ireland, many more of us seeing some sunshine here, the chance of rain limited towards especially northern isles. would not be talking about warmth here, nil —— nor will you and the western isles, near 30 in the very warmest

parts of south—east england. high—pressure right across us going into monday, there is an area of low pressure that will start to slide a cold front towards northern areas and particularly getting closer towards the north and north—west of scotland with a freshening breeze. elsewhere though, with the sunshine, light winds, temperatures hit out more and you will see temperatures well into the 20s and the novus —— warmest parts of scotland, and the low 30s are not as parts of england certainly, but not far from that the hottest parts of wales as well. it does mean we have a heat wave under way through parts of england and wales will stop the weather front though slips more across scotland and northern ireland on tuesday with a greater chance of seeing some rain. is that move southwards, tuesday into wednesday, it will weaken with hardly ever rain left on it onceit hardly ever rain left on it once it reaches southern rangers, but it bring somewhat cooler air further south. behind the weather front cooler, head of it on tuesday, perhaps even hotter still, low 30s again in south—east england. is that with a front move south, temperatures take a

brief dip. stays very warm across southern areas him beyond that and then late into the week in the following weekend as high—pressure slips away eastwards, low pressure may develop towards our west. it may allow another burst of heat to come our way from the south and particularly across southern parts of the uk. that is one to watch. so for next week, we start very warm to hot, there will be a heatwave continuing through parts of england and wales, then turning cooler from the north, england and wales, then turning coolerfrom the north, but barely cooler across southern areas, before we are watching that potential for something perhaps even hotter to arrive, especially in southern areas late in the way, more especially into the following weekend. that is very much the focus from now on on weather for the week ahead. keep watching.
