from the latest explosive eruption of mount kilauea volcano. people have been warned to get away from a sulphur dioxide cloud, which is killing large swathes of vegetation. the volcano has been erupting for three decades, but there's been nothing like this since the 1920s. a year into robert mueller‘s investigation into russian interference in the us election, and possible collusion with it by the trump campaign, the president has again called the inquiry a witch hunt. the special counsel has requested an interview with mr trump, but the terms and date have not been agreed. president trump has rejected claims that a peace deal with north korea could be modelled on the agreement which brought an end to libya's nuclear programme. the idea, suggested by his national security advisor, had alarmed pyongyang, which threatened to pull out of the summit planned forjune. now on bbc news, hardtalk. hello and welcome to hardtalk.

i'm shaun ley. brazil was one of the success stories of the early 21st century. under president lula, rapid economic growth combined with radical redistribution of money to the poor. succeeded him, but under her presidency, the economy faltered. in 2016, she was forced from office, accused of fiddling the figures to boost her chances of re—election. well, now she's here in london drumming up support for lula's bid to be re—elected president — only he's currently in a prison cell in brazil having been convicted of corruption. so are they the saints or sinners of brazil's political class? in support of your predecessor,

the man all brazilians know as lula. why are you so confident that he could be president again? well, let's. .. let's deal with two things that you have raised there. the first is you have talked about the reality. the reality is he is in prison at the moment, he is serving a prison term for corruption, and the courts, at the highest level, have said that his appeals have been exhausted. he cannot, if he is a convicted prisoner whose appeals have been exhausted injail, be a candidate. that's the reality under the brazilian law. how can it be a coup if all the procedures of the law have been observed 7 you make two questions. i must interrupt you.

he was not tried by the media, he was tried by the courts. no! the supreme court, ultimately. if there was really no case, the supreme court would not have supported this conviction, it would have overturned it. a supreme court, incidentally, of which the vast majority of members were appointed either when president lula was in office, or, under you, five of them were appointed when you were in office. let's — we should... let's talk about — there are two things that have been said about you. the one you're talking about is the impeachment. i want to talk about the impeachment. but let me ask you first about petrobras, where you were the chairman whilst you were the energy minister under president lula. it is said that there were significant sums of money

disappearing from petrobras. when did you realise that that was happening? ah, but this is when you were in charge of petrobras. i'm not asking about when you were president, i'm asking about when you were in charge of petrobras. we mustn't confuse the audience about the dates. please. of course. but let's be clear about what we're talking about. what dates? so why didn't you know?

you're a trained economist, why didn't you spot it? forgive me... all right. well, good accountants can spot these things. you can read a balance sheet. are you saying you saw nothing wrong as a trained economist, with the balance sheets of petrobras during the seven years you were there? forensic accountants would disagree with that. i should imagine that, given the terrible experiences you suffered as a young woman under brazil's military dictatorship, suspended upside down, tied naked to a stick, given electric shocks, democracy, the rule of law must be very precious to you. can i — no, forgive me for interrupting, if i may.

ms rousseff, just so the audience are clear what you're talking about. impeachment. you would still be president of brazil right now, as we speak, had you not being impeached. so this is partway through your second term, congress impeaches you and effectively forces you from office. is there anything that you accept now that you did wrong? you use the word "coup", but every rule was observed. these were votes, publicly held votes. the rules were followed. how can you call it a coup if the rules are followed? well, then why does it allow you to do it to the constitution? you keep saying it was a coup but again, you are worried about how they use the rules.

the fact is, they were rules and they applied them. so you're saying there is a conspiracy between judges and politicians to get you out? aren't you changing the meaning of the word?

if the law is used, that is the law. if you don't like the law, change the law. in an election... is there not a danger that however offended about how you feel you have been treated personally, you may be entirelyjustified to feel offended at what happened to you, but by constantly... let me finish the question. you say it's a personal thing, but the danger is, if you discredit the institutions by constantly accusing them of things, then actually you are undermining public confidence in the whole political system of brazil. and that is damaging to brazilians. why...? we could talk, but we don't unfortunately have time, about the extraordinary corruption enquiry that has been conducted,

the so—called car wash inquiry, that has now resulted in 300 people being charged and 180 people being convicted, of all political parties, and of none, that is clearly a pressing problem for whoever becomes president this year in the october elections to deal with. let me put to you this point. if the workers‘ party, your party, instead of trying to run the past resident again as its candidate, a man who is in prison and has been convicted, wouldn't you be better serving your cause by fielding a new candidate, somebody of the teacher, not a man in his 70s who is of the past? let me ask you, finally then, if the presidential election goes ahead, ms rousseff, without lula as a candidate, because they keep him off the ballot paper, should brazilians accept the result? i think the answer, then... bt being the workers‘

party, your party. i think the answer to my question, then, is that brazilians should not accept such a result. dilma rousseff. thank you. thank you for being with us on hardtalk. hello there. well, for most of the uk, thursday was a glorious, sunny, dry day.

saw so many weather watcher picture scenes like this one, in warrington in cheshire, of a flowerful field and shrubs, with the blue skies above, and a lovely end to the day with some gorgeous sunsets. but, like the last few nights, temperatures really falling away under those clear skies, particularly across eastern scotland. for much of england and wales, close to freezing in one or two places, with a touch of frost in fact, but not so much for the north and west of the uk. in western scotland and northern ireland, here a veil of cloud will continue to move in from the atlantic, so it'll be less cold here to start to friday. a chilly start elsewhere, another lovely sunny one expected for england and wales. more cloud, though, across scotland and northern ireland could spoil things a little bit bit. some holes still, with sunny spells, and those temperatures up a notch, i think, compared to thursday, around 19 in the south and the east. high pressure still the dominant feature of our weather as we head into the weekend, but weather fronts never too far away from the north—west.

so for saturday itself, there's some big football matches going on. top and tail of the country, it looks like it'll be fine and dry for all of them, and, of course, the royal wedding in windsor. a cool start with those temperatures rising quite quickly through the afternoon and we should see a top ten of 20 or maybe 21 with good sunny spells. this is the picture for saturday, a cool start, clear skies to start, lots of sunshine around. a little bit of fairweather cloud just bubbling up here and there. close to the west of scotland, though, these weather fronts will be floating, bringing thicker cloud and maybe the odd spot of rain. most places should be dry, and temperatures up a notch still, maybe 21 or 22. as we get on into sunday, though, looks like these weather fronts will begin to make inroads across scotland and northern ireland. so here a cloudier, breezier day, with outbreaks of rain for northern ireland and western scotland, maybe pushing further southwards and eastwards, but i think some parts of northern scotland should see sunshine. for england and wales, another gorgeous day on the cards

with temperatures reaching highs of 22 or 23, but a bit cooler further north and west, because of the cloud and rain. similar picture as we head on into the start of next week. high pressure still dominant but still these weather fronts plaguing the north and west, so outbreaks of rain in northern ireland into northern and western scotland. the further south and east that you head, it should be dry and bright, with plenty of sunshine. could see the odd sharp shower developing in the south—east later on, and those temperatures even warmer — 23 or maybe 2a celsius. hello, this is the briefing. we are live from windsor castle. i'm sally bundock. we are bringing you special coverage of the build—up to saturday's royal wedding. counting down to the picture—perfect match, prince harry and meghan markle prepare for their big day. we will have the latest on last—minute rehearsals. with thousands of royal fans

expected to line these streets, the question everyone is asking is who will walk meghan down the aisle, after she confirms her father is recovering from a heart operation. and we will meet people from meghan‘s home town in the usa, where her old school, neighbours and friends will hold a unique party for the royal couple.
