this is the briefing. i'm sally bundock. our top story: back to work at westminster. british mps are set to return to parliament after the supreme court said its suspension by borisjohnson was unlawful. president trump faces a formal impeachment inquiry over allegations he asked a foreign power to help damage a political rival. critics say he's violated the constitution. climate change could leave hundreds of millions at risk of flooding by the end of the century. a fresh warning from the un. and the boss of wework steps down with immediate effect, amid investor worries over his leadership style at the office rental firm.

good to have you with us. we will have a visit —— busy programme today. also in the programme should frequent flyers pay higher taxes to help tackle aviation emissions? is this just another change that we will get used to, like paying for plastic bags? tell us what you think, just use the hashtag #bbcthebriefing. let's get started. we start here in london where business will resume in the house of commons in a few hours‘ time. it follows that dramatic

and historic ruling by the supreme court that borisjohnson‘s decision to suspend parliament for five weeks was unlawful. the prime minister said he profoundly disagreed with the judges but would respect their decision. a senior government official said that borisjohnson spoke to the queen after that ruling, but would not reveal details of the conversation. our political correspondentjessica parker has been following events. parliament is opening up again. the media tenants are making a return. westminster coming back to life. it wasn't his plan... i have the highest respect of course for the judiciary and the independence of oui’ judiciary and the independence of our courts, but i must say i strongly disagree with this judgement. and in the end, it wasn't his call. the decision to advise her majesty to prorogue parliament was

unlawful. so mps are coming back to this place, now what? well, things are this place, now what? well, things a re pretty this place, now what? well, things are pretty changeable. but you can expect as the commons chamber reopens for business, that there will be efforts to lob some difficult questions that this government and to put borisjohnson under intense pressure. however, it appears the opposition may refrain from trying to bring down the government and trigger an election right away, but mps who felt silenced are ready to make some noise. a parliament has to exert now its authority, it has to be brave and bold and the prime minister has to reach out because there isn't any other way across the aisle to seek a compromise. have you embarrassed the queen? boris johnson is compromise. have you embarrassed the queen? borisjohnson is resisting calls to resign. returning to westminster today, he'll have to face the music. jessica parker, bbc news.

so, what might happen next? we do know that parliament will now resume this morning. the queen is then due to set out the government's future plans at the state opening of parliament on october 14th. there are just three weeks before the prime minister is due to go to brussels for an eu summit on october 17th. in that time, he says he's hoping to negotiate a new brexit deal with the eu. borisjohnson is still insisting the uk will leave the eu two weeks later on october 31st, come what may. but at the moment, if he doesn't get a brexit deal approved by parliament, by law, the government has to ask the eu for another brexit delay. but it's probably fair to say that a lot could change between now and then. with me now is tony travers, a professor at the london school of economics. afamiliar a familiarface a familiar face on the briefing. good morning, tony. good morning.

what is your reaction to the supreme court ruling? it was a bit of a shock, we could say. politically, i don't think anyone was expecting the unanimity, effectively making the prorogation void. in fact, it was an 11-0 prorogation void. in fact, it was an ii—o vote by the supreme court, and what that does is to require parliament, it made the parliament prorogation void, it meant that the session had not ended, john bercow, the speaker will meet at 11:30am. that starts the whole process again, either to get the government to reveal information or change their behaviour in other ways? the prime minister could go to the queen and ask for prorogation, because she has the queen's speech. there could be

prorogation? there has to be, because this one does not exist according to the supreme court and lady hale. it is normal practice, not normally for as long as has happened on this occasion. so think they will have to be another, shorter prorogation, and then another queen's speech. boris johnson's reaction was i don't ee, johnson's reaction was i don't agree, but we will adhere to this. no apology, no signs of any thoughts of resignation, he's saying let's get on with brexit, we are leaving october 31, let's just crack on with business as usual. what's your point

of view of the fallout? i'm not sure it makes as radical a difference to the timetable otherwise heading towards the 31st of october as one might have expected, because in the end, yes, parliament will meet, but it won't change any other fundamentals. from the politics and law perspective? one of the most intriguing aspects was that the court not only made the judgement it did but decided it was going to step in as did but decided it was going to step inasa did but decided it was going to step in as a sort of reverie of the relationship between the government and parliament, lady hale did bring forward a 17th—century example, it does happen from time to time, that is what makes it so remarkable. if you look at the papers this morning, they come out those in favour of brexit thinking it is a bad thing that the supreme court did this,

those against it think it was spot on. great. the papers are very polarised. it's a culture war. tony very much for your perspective on all of this. we will look at the papers later in news briefing. we will dojust the papers later in news briefing. we will do just the headlines later. —— we will go through the headlines later. in washington, members of the democratic party in congress have launched a formal impeachment inquiry against president trump, accusing him of seeking the help of a foreign government to smear a political rival. he has acknowledged withholding military aid to an american ally, ukraine, and pushing the country to investigate joe biden, frontrunnerfor the democrats for next year's presidential election. but, mr trump says withholding the funds was not done to put pressure on ukraine. this from our north america editorjon sopel. new york in september,

when the leadership of the world converges on the un to speak. but one conversation is causing donald trump extreme difficulty, and the heat is intensifying. injuly, he phoned the newly elected ukrainian president volodymyr zelensky, and it's alleged donald trump demanded an investigation into his democratic presidential rival, joe biden, and his son's business dealings in the country as the price for receiving us military aid. no dirt, no aid, is the suggestion. the president denies wrongdoing, but his account of the call has changed continually as the questions have piled up. i think it's ridiculous, it's a witch hunt. i am leading in the polls, they have no idea how they stop me. the only way they can try is through impeachment. this has never happened to a president before. there's never been a thing like this before. it's nonsense and when you see the call, when you see the readout of the call, which i assume you'll see at some point, you'll understand. that call was perfect. joe biden is the democratic party front runner. he is leading donald trump in the polls and says the president this time has gone too far.

the president does not comply with such a request to the congress. he continues to obstruct congress and flaunt the law. donald trump will leave congress, in my view, no choice but to initiate impeachment. that would be a tragedy, but a tragedy of his own making. with the pressure on, donald trump has said he will declassify the phone call and release a full transcript, but too little, too late. it won't be enough to stop the democrats pressing the nuclear button and pushing for impeachment. the actions of the time residency revealed the dishonourable fact of the president's betrayal of his oath of office, betrayal of our national security, and betrayal of the integrity of our national elections. therefore today i'm announcing the house of representatives is moving forward with an official impeachment enquiry. it is hard to overstate the significance of this move by the democrats, and one that the leadership had been very wary about.

a ball has been set rolling with uncertain consequences. democrats will hope this brings about the end of the trump presidency, what they fear is that it will galvanise support for him and lead to his victory in 2020. john sobel, bbc news, new york. we will bring you more on that story when we can. let's brief you on some of the other stories making the news. the spanish tenor, placido domingo, has withdrawn from all future performances at the metropolitan opera in new york. he's been accused by several women of sexual harrassment, which he denies. in a statement, the singer, who's 78, said he was concerned his presence on stage would have distracted from his colleagues' work. robert hunter, the man behind many of the lyrics for the grateful dead, has died. he was 78. with guitaristjerry garcia,

he co—wrote some of the dead's best—loved songs — including brokedown palace, ripple, and jack straw. he also wrote lyrics for bob dylan. cause of death has not been disclosed. he died at his home in california. slovenia's national airline, adria, has suspended all flights as it looks for more funding to continue operating. it's asked for government funding so it can carry on. the airline has more than 20 aircraft but leasing companies have repossessed many of its planes. it comes just days after the collapse of the travel giant thomas cook. un scientists are due to publish their latest study on how climate change is affecting the world's oceans. the intergovernmental panel on climate change will warn that hundreds of millions of people could be at risk of flooding by the end of the century. matt mcgrath reports. for decades, the disease have been oui’ for decades, the disease have been our best friend in the fight against climate change, soaking up carbon

dioxide and access heat. the scale of verbal warming means we have gone too far, say scientists, and are wreaking havoc on marine ecosystems. coral reefs play a crucial role, serving as nurseries for a vast number of species and protecting the shoreline from storms. rising temperatures have ta ken shoreline from storms. rising temperatures have taken a huge toll on these delicate creatures in recent yea rs, on these delicate creatures in recent years, with devastating consequences for the corals. this is like losing all the trees in a forest. if you cut all the trees down ina forest. if you cut all the trees down in a forest, remove the trees, hey, there are no birds, there are no insects, it's losing the base to the ecosystem. that's a tragedy at an environmental level, if you go further than outcome of these coral reefs provide important services for humans. they break important wave breaks, they protect islands... the ipcc report is likely to paint a bleak picture for the future of creatures like corals. it is dark

thought that without massive cuts in carbon emissions, creatures like these may only be found in the borough trees or public aquariums stop —— the grateful dead. with rising temperatures, ocean levels could rise and flooding could affect millions of people worldwide. stay with us on bbc news. still to come: extreme weather causes chaos at cycling's road world championships here in the uk. both riders were able to continue their races. benjohnson, the fastest man on earth, is flying home to canada in disgrace. all the athletes should be clean going into the games. i'm just happy that justice is served. it is a simple fact that this morning, these people were in their homes.

tonight, those homes have been burnt down by serbian soldiers and police. all the taliban positions along here have been strengthened, presumably in case the americans invade. it's no use having a secret service which cannot preserve its own secrets against the world, and so the british government has no option but to continue this action even after any adverse judgement in australia. concorde have crossed the atlantic faster than any plane ever before, breaking the record by six minutes. you're watching the briefing. the headlines: british mps are set to return to parliament after the supreme court ruled its suspension by borisjohnson was unlawful.

us democrats have launched a formal impeachment inquiry against donald trump over claims he pressured the president of ukraine to investigate his political rivaljoe biden. let's stay with that now. joining me now is peter zalmayev, a kiev—based political analyst. let's get a sense of what the reaction has been like in the ukraine to this story. what are people saying about this where you are? first of all, it is a particularly poignant moment for the ukraine which has embarked on a new round of battle against corruption, and now it appears that under donald trump, the us has attempted to use the ukraine for its own narrow political ends. the president is going to meet president trump today,

and is as he is doing so, he finds himself between a rock and a hard place. stay saarland and alienate donald trump or help trump and risk alienating the democrats. especially if they win in 2020. there is an expression, don't step on the same break twice. giving trump what he wa nts would break twice. giving trump what he wants would be election meddling and would therefore be unlawful. as you say, these two leaders are expected to meet on the sidelines of the united nations general assembly in new york. i wonder if that meeting would still go ahead as planned given what is going on within politics on capitol hill. that is the million—dollar question. donald trump isa the million—dollar question. donald trump is a unique president in american history and anything can be expected. it is not out of the question that he will use that podium to try once again to double down on his argument that what he did, what he said during his phone

calls, and there were eight of them, there was nothing unlawful, nothing illegal about them, and so he will use that opportunity once again to make the point and try to deflect from accusations that in fact what he did was to try to pressure the ukrainian leadership and to make the $300 million aid to ukraine depend on volodymyr zelensky‘s willingness to co—operate. let me mention one more point, why it is a particularly tricky women for the ukraine. it comes tricky women for the ukraine. it co m es after tricky women for the ukraine. it comes after the 2016 presidential election in the us when certainly ukrainian politicians were implicated that led to the downfall of trump's campaign chairman paul manafort. that was indirectly helping trump's opponent. once again, ukraine is facing a momentous choice, but it is how to see how one would give trump what he wants after

this has blown into such a scandal thatis this has blown into such a scandal that is likely to lead to an impeachment of the american president. very briefly, this has really put volodymyr zelensky in the global spotlight, he is newly elected, he is brand—new to politics. he was out of nowhere as well, quite a controversialfigure. how is he likely to handle this, do you think? i think the realfavour that volodymyr zelensky can give washington is to demonstrate that ukraine has an independentjudiciary and it has begun to operate, and he, ido and it has begun to operate, and he, i do not believe, will be co—operate —— cooperative with donald trump. peter, thank you and good to talk to you in here. interesting. now let's focus on all the sports stories. hello. iam mark i am mark edwards. we start with football, and the italian juggernaut that isjuventus had a mighty scare on tuesday as they had to come

from a goal down to beat newly promoted brescia, the home side taking a shock lead through this alfredo donnarumma rocket after just four minutes. by half—time, juve were level through an own goal before miralem pjanic won it for champions with this lovely long—range effort. the win takesjuventus back to the top of the table, a point ahead of inter milan. barcelona are back to winning ways following their shock loss to granada at the weekend. they beat villareal 2—1 at home, but something of a pyrrhic victory as they lost lionel messi to injury on his first start of the season. the newly crowned fifa player of the year set up antoine griezmann for the opening goal, but came off at half—time with a thigh injury. arthur had put barca 2—0 up before a santi cazorla goal brought the visitors back in contention. barca, though, climb up to fourth. samoa got their rugby world cup under way with a bonus point 311—9 win over russia in kumagaya. but the islanders were made to work for it by a spirited russian side. russia were actually ahead

at half—time after two penalties from yury kushnarev. samoa were down to just 13 men for part of the first half after two ferocious and dangerous tackles from rey lee—lo and motu matu'u. but with a full compliment back, samoa ran in five second—half tries to finish comfortably in the end. wednesday's match is fiji against uruguay. real madrid could go top of la liga later. that's if they beat newly promoted osasuna and other results go their way. madrid have won three of their six games in all competitions so far this season. their 3—0 defeat to paris saint—germain in the champions league has once again raised questions about zinedine zidane's future. he's struggling with a host of injuries, which he puts down to the pressure modern footballers are under. translation: i remember when i used to play. we played a0 to a5 games. now they are playing 60 games. it is

like playing two seasons in one. maybe that's is what makes the difference. football has changed. having to play 60 to 65 games makes you having to play 60 to 65 games makes y°u pay having to play 60 to 65 games makes you pay dearly for it and we are paying dearly for it now. tennis, and there are quarterfinal places up for grabs at the wuhan open in china on wednesday. among those through to the last 16 is the top seed ashleigh barty, but she had to come from a set down to beat the 2017 champion caroline garcia. the unseeded frenchwoman took the first set 6—a, but barty won the second to level the match and set up a decider. the third set was very one—sided with barty taking it 6—1. the world number one will shortly be facing sofia kenin of the usa in their third—round clash. finally, after a brilliant summer of sport in the uk with the cricket and netball world cups and the ashes, to name but a few, cycling's road world championships might be wishing they scheduled their event for a bit earlier in the year. have a look at this crash—bang—wallop sequence courtesy of a substantial downpour. we're at the men's under 23 time trial in yorkshire on tuesday

and relentless heavy rain saw an early bath for one rider. and look away now if you're squeamish — the horrible conditions causing this crash as well. ouch! you can get all the latest sports news at our website. that's bbc.com/sport. but from me, mark edwards, and the rest of the sport team, goodbye. thank you for that. i asked you earlier of your view i story online. our environment analyst has put forward this story about introduce frequent flyer levy to fight emissions. you can see this on the bbc news app. also, it is online as well. this is all coming from a committee on climate change suggesting that this frequent flyer levy to those who travel a lot by air. you may remember recently that

greta thunberg delivered a powerful speech at the united nations this week. she travelled from sweden to the us by a vote to make a point. you have been in touch to tell us what you think. paul says, if it really is a frequent flyer tax, and it is just another tax, punishment for everyone. if you fly more than three times a year, tax these passengers. we have another viewer who just says, yes, passengers. we have another viewer whojust says, yes, they passengers. we have another viewer who just says, yes, they should. passengers. we have another viewer whojust says, yes, they should. it is as simple as that. go for it in the same way that there is, in the uk, you paid to buya the same way that there is, in the uk, you paid to buy a plastic bag if you need one when you go to the supermarket. we have all adjusted to that change in behaviour. jeff says, however, which sector of the government do you feel confident in with taking on the task of managing and ultimately controlling the planet's weather systems and climate? i don't think anyone can control whether systems or climate, thatis control whether systems or climate, that is the problem. lots of other

comments coming through, which is great. an interesting twitter handle, we do realise such attacks would price more people out of flying and would serve as a right to pollute tax for the richer part of the population. is that correct? another one says, no, because i think travelling by train, drawn by a diesel locomotive can bejust think travelling by train, drawn by a diesel locomotive can be just as bad. not to mention that the electricity used by electric locomotives reduced by power plants that are running on coal. on cue so much for all your comments. there are plenty more. here is a story to mention before we move on to business. the last selection of pink diamonds in the world are heading to auction in london where they could fetch up to £100 million. the mine in australia which produces them and 90% of the world's pink diamonds is closing next year. this will make pink diamonds the most sought—after gem in the world.

that is the expectation. so there you go. if you have got some spare cash, they will be on sale in london soon. i will see you soon for the business briefing. hello there. well, september had been on course to be a dry—looking month across the south of the uk until our most recent spell of very unsettled weather. yesterday, an area of low pressure. heavy rain, thundery downpours. those downpours really did come down very heavily. this was the scene near the bbc in oxford circus. you can see some very heavy rain there. that was quite typical for many of us. a month's that was quite typical for many of us. a months worth of rain, so a wet septemberfor some us. a months worth of rain, so a wet september for some in the south. it was quite wet across northern areas as well. we are all in the

same boat in a way, a soggy boater that is. rain continuing to come down on the southern parts of england and wales, some strong winds. the wind is light of a northern england and scotland. rain here as well. one way or another, a pretty start to the day on wednesday. subtle improvements through the afternoon before the next weather system comes in late in the day. rain at times on wednesday. strong winds and they will either through the day. they will try to brighten up, some sunny spells around the afternoon and heavy showers and the next batch of rain moving its way into northern ireland. temperatures not too bad at this stage, eyes typically around 17 to 19 celsius — highs. more rain on the way for thursday, another area of low pressure pushing these weather fronts across the country. as rain is taken away, we still have a flow of fairly cloudy weather coming in with further heavy showers and thunderstorms at times as well. another unsettled day, still windy

and temperatures just falling a bit in scotland and northern ireland. it is forecast to get a little cooler here, that will change for england and wales. friday, another day, more rain as well. it pushes north and east and that clear through, it will be followed by for the showers. another blustery day and starting to get cooler. 1a and 15 degrees for scotla nd get cooler. 1a and 15 degrees for scotland and northern ireland. 16 to 18 in wales. temperatures coming down by a degree or two. rain at times and still quite windy over the weekend. temperatures 15 to 18 degrees.

this is the business briefing. i'm sally bundock. politicians head back to westminster after the uk's highest court rules it was unlawful for the prime minister to suspend parliament. our business leaders any wider as to what will happen with brexit? we will assess the future. —— any wiser? and the boss of wework steps down with immediate effect amid investor worries over his leadership style at the office rental firm. and on the markets: they have the jitters. declines in asia on the news of impeachment proceedings in the us being on the

way.
