to know in global news, business and sport. and you can be part of the conversation. after a us couple sue their adult son because he refused to move out, we're asking if you think parents should let their kids live with them as long as they need to? tell us what you think — just use the hashtag #bbcthebriefing. north korea has agreed to let in a team of south korean journalists watch the dismantling of its nuclear test site at punggye—ri. pyongyang had earlier refused them visas, though international experts and journalists from other countries, including the us, had been invited. the move comes as president moonjae—in visits washington to try to salvage plans for a summit next month between kim jong—un and donald trump. president trump earlier said there was a substantial chance the summit would not go ahead.

david willis reports. by by the time president no—one had arrived at the white house, a meeting to set the agenda for an historic summit had morphed into a discussion about how to save it. i don't want to waste a lot of time and i'm sure he does not want to either. so there is a substantial chance that won't work out, and that is ok. it does not mean it won't work out over a period of time. is ok. it does not mean it won't work out over a period of timem may not work out forjune i2. work out over a period of timem may not work out forjune 12. the us wa nts may not work out forjune 12. the us wants north korea to completely dismantle its nuclear weapons and the demolition of the test side in the demolition of the test side in the north—east of the country is due to ta ke the north—east of the country is due to take place sometime this week, with journalists including to take place sometime this week, withjournalists including now some from south korea, present to watch. but having talked about

denuclearisation, kim jong—un threatened to cancel the summit and walk away. an about—face that followed a trip to beijing, prompting president trump to conclude that the chinese president may have had a hand in it. president xi isa may have had a hand in it. president xi is a world—class poker player. and i probably maybe would do the same thing he would do. but i will say this. there was a somewhat different attitude after that meeting and i am a little surprised. president no—one was very happy about the possibility of peace on the korean peninsula but some here are wondering if he overstated north korea's willingness to strike a deal. it is equally possible that american officials simply misunderstood the signals they received from the north. among them, the release of american hostages. yet despite the doubts, one of the summer's architects was more upbeat. kimjong—un summer's architects was more upbeat. kim jong—un after the meeting president trump agreed to undertake it. we work to find a date and

location those set. and since then we are driving hard. we are working to make sure there is a common understanding of what the content that will be discussed are but i am optimistic. all of this coincided with the release of a commemoratives are coin to market the first—ever summit between the leaders of the united states and north korea. whether it will prove embarrassingly premature, it remains to be seen. it's been a year since a suicide bomber killed 22 people at a pop concert in manchester in northern england. many of those who died were children. a few hours ago, another concert was held in honour of the victims. earlier, the prime minister and the duke of cambridge attended a memorial service in the city, where they led a nationwide minute of silence. keith doyle reports. at 1031 last night, bells rang out across manchester to mark the

moment, exactly one year ago, that a—bomb exploded and 22 lives were lost. throughout the city, people once again paused in quiet reflection at the end of the day we the people of manchester remembered those who died one year ago. but also celebrated this city's remarkable spirit. earlier, that spirit was on display in a blaze of colour and song. in albert square, singers from around manchester were led by a choirformed of those singers from around manchester were led by a choir formed of those who survived the attack. voices in unison as a city came together. joyous songs from oasis were sung. manchester could not be prouder. hate will not win. because love sings louder. and a poet had the

crowd whipped up like a rock star. everyone has pulled together and is being supportive of each other. holding hands and talking about their experiences. it is nice to see. everyone in this crowd is connected to each other. this is a great city. it is almost a happy day, as much as it is sad. it is lovely for everyone to come together. yesterday, the prime minister and the duke of cambridge attended a service of remembrance at manchester cathedral. among the congregation, multi faith leaders and many who survived the attack. 22 candles will tribute to the victims. candles made from the remnants of hundreds left around the city in the aftermath of the attack. throughout the day, tributes were made in many

different ways. on social media, from wayne rooney. and coronation street stars shed a picture with one of the big. and then there were spontaneous displays of solidarity. here on a manchester tram. # are we all somebody to lean on. but it was last night that the city apparently showed its resistance through colour, light, music andjoy. yes, there were tears that this was an extraordinary day of remembrance and celebration, in an extraordinary city. # all you need is love. # love is all you need. let's brief you on some of the other stories making the news. the most senior roman catholic priest convicted of covering up child sexual abuse, the australian archbishop philip wilson, has announced he'll step aside from his duties, but isn't resigning. the archbishop of adelaide, who faces up to two years in prison, said he was still considering the court's reasons for thejudgment.

south korea's former president lee myung—bak, who was detained in march on charges of taking bribes while in office has arrived for the first court hearing in seoul. lee, who was president from 2008 to 2013, is accused of accepting bribes worth about 10 million dollars from south korea's national intelligence agency and businesses, reportedly including samsung. venezuela has expelled the top two us representatives in the country after the americans criticised the re—election of president nicolas maduro. mr maduro said the us charge d'affaires and another senior diplomat had been conspiring against his government. the us state department rejected the allegations. mark zuckerberg appeared in front of the european parliament on tuesday, to answer questions over concerns about data privacy

and other problems on his social network, facebook. but while mr zuckerberg apologised again, there were few answers to any of the questions. kulveer ranger is the vice president of strategy & communications at atos. hejoins me now. i know you watched his appearance in front of us politicians and this one. it was an extraordinary appearance because he seemed to be asked many questions that didn't really give many answers.|j asked many questions that didn't really give many answers. i think it is unfortunately that the format overtook the concept. the meps were asking questions one out of the other. the first hour was spentjust lining up questions and the last 25 minutes, mr is a good bird managed to get some answers in but would probably pick and choose somebody game. probably not a satisfactory grilling as we would expect it to

be. what do they want to get out him, that he has not previously provided to the us senate and congress? they were trying to probe into what is the thinking of facebook. what is his thinking about some of the issues they face, things like fake news and political interference. issues such as personal data. cambridge analytic of being the primary example of data being the primary example of data being taken from facebook and used to influence their thinking. these are serious issues and they are trying to understand what is the response of facebook to these issues. best they got was that they are sorry. quite rightly, facebook are sorry. quite rightly, facebook are saying they are sorry about this but the question is what is the plan for the future. can they reassure politicians but will it be something that needs to be done by them all to them in terms of regulation that will improve the situation? them in terms of regulation that will improve the situation7m them in terms of regulation that will improve the situation? it has been a while the data privacy to bar

called. it does not seem that much has changed. am i wrong?|j called. it does not seem that much has changed. am i wrong? i can understand you saying that because we seem to have a scandal and an issue and then it all goes away. but mark zuckerberg has been in front of us politicians and european politicians. the tectonic plates around data privacy are moving. or the big technology organisations are looking at where this will go. this is something quite serious in the minds of both the public as well as politicians who want to be reassured. i know we have new regulation, the general data protection regulation, that will come in at the end of this week. i think that is another serious change in terms of how people will be protected and that personal data protected. i know you will return shortly to talk through the papers including that story. a historic referendum takes place on friday on whether to reform ireland's abortion laws. the vote will decide whether to repeal a constitutional amendment that effectively bans terminations.

it will be the country's sixth referendum on the issue. currently, abortion is only allowed when a woman's life is at risk. nuala mcgovern reports from dublin. she said, you know, your baby has a brain stem so its heart is beating 110w brain stem so its heart is beating now but it will not live. i started to think about this baby and what it would be like for this baby to be born. and i could not imagine it being a very pleasant way to be born and then die. so i started to think that this was probably a pregnancy that this was probably a pregnancy that we would end early. in ireland, abortions are permitted only when the life of the mother is in danger. she was given a choice. she could be looked after in ireland and tell her baby died, or her medical paperwork

could be sent to liverpool and amy and her husband could follow the paperwork to the uk for a termination. amy's story is just one in the debate about abortion. that there are so many stories on both sides of the issue. it is a highly emotive and sensitive topic that is dividing the people of ireland. the campaign is in full swing as it has been for months. leading the no campaign is cora. on may 25 we will be talking about something that will end the life of a baby for any reason up end the life of a baby for any reason up to 12 weeks to go i don't believe there is any other difficult situation in life, in society, where we advocate ending the life of a human being in order to bring about a positive response. designed to protect both the mother and her unborn child. these laws work. to not only ignore but to then deny the result and branded as a failed

experiment is extremely horrifying and offensive to someone like me. human rights have been part of the no campaign. but many are asking whether this campaign is linked to the history of religion and catholicism. since the foundation of the state, there have been a silencing of anything to do with sexuality, the bodies of women, fertility. over the last 100 years, women have been put into institutions. pregnant women outside of marriage. into mother and baby homes. and that was all about marginalising and keeping secret what was considered a shame. marginalising and keeping secret what was considered a shamelj wonder that whatever the outcome, if it will become an catalyst for the people of this country to talk to friend and neighbour and debate what sort of future island they want to live in. —— ireland. stay with us on the briefing. also on the programme:

how heavy is all the water in the world? these satellites are going to tell us. this morning, an indian air force plane carrying mr gandhi's body landed in delhi. the president of india walked to the plane to solemnly witness mr gandhi's final return from the political battlefield. will ireland has voted overwhelmingly in favour of gay marriage. in doing so, it's become the first country in the world to approve the change in a national referendum. it was a remarkable climax to what was surely the most extraordinary funeral ever given to a pop singer. it has been a peaceful funeral demonstration so far, but some of the police are tear—gassing the crowd — we don't yet know why. the pre—launch ritual is well established here. helen was said to be in good spirits butjust a little apprehensive. in the last hour, east timor has become the world's newest nation. it was a bloody birth for a poor

country and the challenges ahead are daunting but for now, at least, it is time to celebrate. you're watching the briefing. our headlines: and our top story — president trump says there's a risk that his planned summit with the leader of north korea won't go ahead next month. church bells have rung out in manchester, marking the exact moment a year ago when a bomb exploded at a concert by the singer ariana grande — killing 22 people. two satellites have been launched into orbit to measure the weight of the earth's water. scientists will use the data to monitor the climate and predict future changes.

caroline rigby has more. blasting off from california, the joint american—german mission aboard a spacex rocket, the launch marks the second stage of the revolutionary project, aimed at measuring the weight of water on earth. a resource that covers three quarters of the planet's surface and infiltrates deep below. civilisations are built around it and continue to depend on it today. water is critical to everything in life. for our health and for us to have agriculture and for us to live the way we live today. what this will provide us is a global measurement of water in all of these phases. these measurements allow us to measure the water more effectively. the gravity recovery and climate recovery follow—on, or grace satellites, replace a pair that stopped working last year. flying 220 kilometres apart, they will perform a perfectly synchronised orbit around earth. as the lead spacecraft lurches through the gravity field,

the second will measure any changes in mass caused by oceans or ice fields. the sea is rising and the polar caps are melting and all of this has long—term ramifications. there are tools now to monitor and estimate what the future may be like. the data will not only allow scientists to track how the world's water is changing but also how its climate is evolving. that in turn will help communities and governments avoid scenes like this or plan more precisely for the future. here's our briefing on some of the key events happening later. a zimbabwean parliamentary committee has summoned former president robert mugabe to give evidence on about diamond corruption alleged to have cost billions of dollars during his rule. mr mugabe, who was ousted from office in november,

hasn't confirmed yet whether he will appear. later in london, britain's theresa may will meet the belgian prime minister charles michel at downing street. and in washington, the us secretary of state mike pompeo has a day of high—level meetings starting with the chinese foreign minister wang yi, followed by talks with the foreign ministers of germany and japan. all now or not a tory president saying that there is a risk that his plan summit whitnall career would go ahead next month that matt moore now on our top story. first of all, let us on our top story. first of all, let us talk about north korea has agreed to let in a team of south korean journalists to watch the dismantling ofa journalists to watch the dismantling of a nuclear site. previously he has said it would not let them in. how important is this? i think it is

important is this? i think it is important for the fact that it was pa rt important for the fact that it was part of the agreement between the north korean government and the south korean almond, moonjae—in, during the summit they held last month in the demilitarised zone —— president. one of the specific promises to come out of that from the north korean leader was that he would allow international journalists, including south korean journalists, including south korean journalists, to witness this dismantling of the nuclear test facility. it looked, last week, were in the last few days, in fact, as though suddenly pyongyang was relenting on that promise. and that raise questions as to whether north korea was going to relent on a lot of things it had committed itself to during that summit. that has now been reversed. we understand eight south korean journalists are or are in the airon south korean journalists are or are in the air on a government play in flying to a city on the east coast of north korea, where they will link up of north korea, where they will link up with the other group of international journalists already there, and together they will head

by train, about 500 kilometres north to the site. let us talk about president troubles toppie has come out and said to reporters that there isa out and said to reporters that there is a risk of these some are not doing her —— president trump, he has said. what is the cause of this slight turn? it appears in the last few days, according to reports in us newspapers, that president trump has been asking his advisers whether this summit in singapore with kim jong—un should go ahead or not. it appears that president trump has realised the high expectations and the hope that there could be a big one—time deal with north korea over its nuclear weapons at the singapore summit was unrealistic and he is not going to get that deal. so he is in extent going to get that deal. so he is in exte nt — — going to get that deal. so he is in extent —— to extend walking back his own rhetoric. it appears, and we are

getting to an extent, that president trump and the north korea is certainly the south korean government all want this summit to government all want this summit to go ahead, but there is concern of saving face and not looking like it isa saving face and not looking like it is a failure after the very high expectations that was that last month. ok, rupert wingfield-hayes, in seoul, thank you very much. now it's time to get all the latest from the bbc sports centre. hello, i'm gavin ramjaun — and this is your wednesday sport briefing. coming up, can lebronjames propel the cleveland cavaliers, to the brink of the nba playoff finals? we have more on his heroic performances so far. and kane's calling for england, as the spurs man is charged with leading the team, at the world cup. the games come thick and fast this time of year in the nba. and there's another huge one on wednesday night in boston. the celtics host the cleveland cavaliers, with the best of seven series finely poised at 2—2. but it's the cavs who have the momentum after a 111—102 win in game 4 on monday. once again lebronjames was the main

man, with a game—high 44 points. it was the sixth time he'd hit more than 40, in this year's playoffs, as he broke the record for the most post—season field goals in nba history. a record that had stood since 1989. simon yates can take another big step towards becoming the first british rider to win the giro d'italia, later on wednesday. yates takes a 56 second lead into stage 17, from riva del garda to iseo. the british rider is now the favourite for the title after safely negotiating the time trial on tuesday. he finished 22nd but maintained a healthy overall lead. defending champion tom dumoulin, who's second in the overall standings, made up time but would have hoped for a lot more given he is the world time trial champion. and arsenal are expected to formally announce unai emery as their new manager later on wednesday, with the spaniard

expected to speak to the media. emery left paris st—germain, where he won one ligue 1 title, and four domestic cups in two seasons in charge. tottenham hotspur‘s harry kane will captain england at the world cup next month. its not the first time the striker‘s worn the armband. he led the side during last year's world cup qualifier against scotland, and then a further three times after that. manager gareth southgate says kane has the "belief and high standards" that will set an example to the rest of the team. previous captains include steven gerrard and david beckham. argentina and manchester united goalkeeper sergio romero, has been ruled out of the world cup due to a knee injury. the 31—year—old has 94 caps for his country, and played every match during their world cup qualifying campaign, as argentina finished third behind brazil and uruguay. romero was named in argentina's 23—man squad on monday, along with fellow keepers willy caballero and franco armani. thank you. we asked you to tell us

about our talking point. we asked you to tell us if it is a good idea for kids to live as long as any two at home. we have had a lot tweets on this. one from chesapeake bay in the usa saying a housing my son, his 27, he could possibly live independently with support but we have talked about it and like being roommates. from the mywee have everything in this world has an expiry period, for kids they can stay until they graduate and then the expiry kicks in —— or buy. that sounds fair to me. plenty of tweets coming. keep them coming. thank you for watching bbc news. wednesday is looking absolutely fine

across much of the country. sunshine on the way and it will feel quite warm as well. this warm spell of weather is here to stay. there will bea weather is here to stay. there will be a little bit of rain around late in the week, but on balance, as we head towards the bank holiday weekend, i think we will keep the warm weather. the jet stream is to the north of us, it is diverging the weather systems away from the uk in the direction of scandinavia. we are to the south of that. look at these temperatures. these are the warm colours. they are engulfing much of the continent. everywhere across europe, more or less, is much warmer than average. this is what it looks first thing in the morning on wednesday. ten in the south. around

seven in the north. the web itself looking sunny, pretty much from the word go. not necessarily close to the north coast. it is what we cool fret. we have an onshore wind and it will feel cooler. the yellow colours compared to the deep orange colour syd ney compared to the deep orange colour sydney south. a temperature contrast in the uk across wednesday afternoon. —— in the south. about 10 degrees more in london. as we head towards the second half of the week, this weather front approaches. it will be swinging out of friends. this could bring a spell of wet weather to southern areas. —— france. it will wales on thursday, could be thunderstorms as well. much of the country on thursday northwoods is enjoying and other fine day. it will be pleasantly warm. temperatures typically around the high teens or low 20s. that wet weather may hang around for a time on thursday. as we go through thursday night into friday, this little weather front will drift further north. it looks as though on friday areas that did not get the

rain on thursday will eventually get at least some. then the weekend is looking promising. we have a plume of warmth coming in from the south, that will be reaching the uk. that will mean one thing, the temperatures will be rising. this is business briefing. i'm maryam moshiri. another apology but very few answers. european lawmakers are disappointed after a grilling of facebook boss mark zuckerberg. and, can jaguar land rover save tata motors? we'll find out later today when the indian carmaker reveals its results. and on the markets, it looks like a negative day for asian markets, following wall street's lead.
