The UK is no longer leaving the EU today.

Brexit day has been postponed - to exactly when remains uncertain.

But where does that leave the parties, merchandise and TV specials planned to mark the occasion?

We've taken an in-depth look.

BBC Breakfast

International Trade Secretary Liam Fox says today may be "MPs' last real chance to vote for Brexit".

Speaking to BBC Breakfast he says there is a risk the indicative votes process started this week could see Parliament trying to "bind us into either extending our membership of the European Union or not leaving the European Union at all".

He adds: "The key thing is to get the agreement through today and... to leave the European Union on time and in an orderly way."

Asked about his views on who would lead the Conservatives - and next stage of negotiations with the EU - following Theresa May's pledge to stand down, Mr Fox says: "There is far too much attention placed on individuals at the moment. The serious issue is can we deliver as Parliament on what the voters instructed us to do way back in 2016."

Shadow Brexit Secretary Sir Keir Starmer says today's motion is a "desperate measure" by the government.

He tells BBC Radio 4's Today programme: "It's not part of the plan... To now cut the deal in half and present half to Parliament."

MPs are not being asked to vote later on the political declaration section of the deal, which outlines the shape of future UK-EU relations.

"Once you strip away the political declaration, you strip away what is going to happen afterwards. The direction of travel - the future relationship.

"We have always said the problem with the deal is that it is blind, it is so thin. Take the political declaration off and it is completely blind. You have no idea what you are really voting for."

Former Tory party leader Iain Duncan Smith says he wishes the government had secured "more substantial changes" to its withdrawal deal with the EU - but has reluctantly come round to supporting it and will be voting for the motion later.

"It is a reluctant decision because I recognise like many of my colleagues that there are some fundamental flaws with this process," he tells BBC Radio 4's Today programme.

"What we face is a Parliament made up substantially now of people who simply just do not want Brexit to take place. That majority makes it almost impossible for us to do anything other than essentially to get what we have on the table..."

Friday should have been the day the UK officially left the EU.

But Parliament still hasn't come to an agreement on the best way forward for Brexit.

Confused?

Here's what's going on.

Theresa May has put her whole deal to Parliament twice in what were called "meaningful votes" to secure her deal, but both times her plan has been voted down by historic margins.

The government today has tabled a motion to be debated and voted on by MPs.

But unlike previous occasions, where MPs have been talking about the entirety of Theresa May's deal, this time it is just the one of two elements - the withdrawal agreement.

This is the legally binding document that sets out the terms of the UK's departure from the EU.

Friday's vote, if it passes, would secure a delay until 22 May. Ministers say the backing is vital if Britain is to avoid a disorderly exit.

There are signs now that many Eurosceptic MPs are ready to say "yes" - not because they suddenly have realised Theresa May's deal is perfect, but because more of them officially realise that it is the clearest break from the EU they can realistically hope for.

Yet her Northern Irish allies are not persuaded. Labour, even though they have sometimes accepted that what's on the table - the divorce deal - will never be unpicked by the EU, will still, in the main, resist.

As things stand, even though some influential Brexiteers believe there is a chance it will get through, it looks like the prime minister is heading for another loss.

But for Number 10, it is another way of extending the road before it finally runs out.

The return to the Commons of the Brexit withdrawal agreement Theresa May negotiated with the EU inspires some dramatic front-page headlines.

And several papers urge MPs to back the prime minister's deal and deliver the result of the 2016 referendum. "This is it. The final curtain. High noon. The last chance saloon," reads a thunderous, full-page Daily Mail editorial.

The message from the Sun's leader column is simple: "Don't betray UK."

Downing Street sources have warned the Daily Telegraph that defeat could trigger an immediate general election to break the current deadlock. But it's a prospect the paper is sanguine about. It is time to let the deal die, it says.

The Daily Mirror reflects bitterly on all that hasn't been done while politicians have spent "two years arguing about Brexit".

House of Commons
Parliament

Parliament does not normally sit on Friday.

Today's vote required MPs to approve a motion authorising the Commons to sit, without the need for a formal division.

Commons leader Andrea Leadsom then announced said the sitting would begin at 09.30 GMT.

Good morning and welcome to our live coverage of Friday's events at Westminster.

MPs will vote again on Theresa May's Brexit withdrawal deal - on the day that the UK was originally meant to leave the European Union.

Parliament will not debate the political declaration on Britain's future relationship with the EU, meaning it will not amount to a third so-called "meaningful vote" on the deal.

And Mrs May is facing opposition from Labour, the Democratic Unionists and some Tory Brexiteers.

MPs will begin to debate the government's motion at 09:30 GMT with the voting due to start at 14:30 GMT.

We're now bringing the live page to a close for a bit until we resume it tomorrow, so here's a recap of what happened today.

We started the day not knowing for definite if Prime Minister Theresa May was going to ask MPs to vote on her Brexit deal for a third time.

Parliament had already rejected the deal twice, and the Commons Speaker, John Bercow, had warned that it could not be brought back without "substantial changes".

But at around lunchtime, the government confirmed it would ask MPs to vote on part of the deal on Friday - the withdrawal agreement - splitting it from the so-called political declaration.

BBC political editor Laura Kuenssberg said Theresa May was essentially asking MPs to turn it into a game of two halves - by voting on the first part of the deal, which sorts out the UK's departure, and leaving the longer term part for the next few weeks.

Mrs May has previously promised Conservatives that she would stand down as prime minister if the deal is passed.

But hopes of her deal passing remain in doubt, with Labour saying it was opposed to the agreement and a number of Tory Brexiteers, along with the Democratic Unionist Party, also signalling their opposition.

The vote on the withdrawal agreement is scheduled to take place tomorrow from 14:30.

A new opinion poll has suggested that Brexit is now the most important issue for Scottish people in the question of whether Scotland should be independent, the Press Association reports.

The poll of 2,000 people was carried out for Progress Scotland, a research group set up by former SNP deputy leader Angus Robertson.

The aim of the group is to identify the policies and arguments that would persuade voters to back independence.

The poll suggests 43% of voters cited Brexit as one of the three key issues they would consider in a Scottish independence referendum.

It was just ahead of the 42% who said the economy was the most important factor.

In 2014, which was when Scotland held an independence referendum and voted to stay, the economy was the main concern and EU membership ranked as only the sixth.

James Cleverly, the deputy chairman of the Conservatives, has been responding to tweets posted earlier by Labour's shadow Brexit secretary, Sir Keir Starmer.

Sir Keir claimed there were four reasons, external why the withdrawal agreement (which the government is putting to a vote tomorrow) and the political declaration cannot be split apart.

However, Mr Cleverly has now posted a Twitter thread disagreeing:

BBC News Channel

The historian and vice-chancellor of the University of Buckingham, Sir Anthony Seldon, said he believed Brexit was the UK's biggest constitutional crisis since 1688, when the Glorious Revolution began.

That revolution ultimately established the supremacy of Parliament over the British monarchy.

Sir Anthony compared Brexit to previous crises, such as the Suez crisis in 1956, but then there was only "a week or two of real crisis", he said.

"This hasn't gone on for a week," Sir Anthony said. "It's gone on for three years."

Asked if the current situation was Suez on steroids, he replied: "Absolutely, and worse."

Sir Anthony added: "The real essence of the problem is that the country voted to leave, but only just - another day it could have gone the other way.

"But these people here in Parliament predominantly want to stay.

"So is Britain a popular democracy, where the people decide the future, or is it these guys here, who are the representatives of the people who voted in general elections? And that's really the nub of the problem."

BBC News Channel

Emma Vardy, the BBC's Ireland correspondent, said the reason the backstop is so disliked is "because it could leave Northern Ireland being treated differently to the rest of the UK".

She said there have been some "ideas floated to try to avoid that scenario and make it a bit more palatable - things like perhaps giving the DUP a role in future trade talks, for example".

She added: "Also a thing called the 'Stormont Lock' which would be giving this place, the Northern Ireland assembly, a say on whether that backstop is entered into and also promises that if NI had to stick by certain rules then the rest of the UK would stand by it and do the same.

"But none of this has really got it over the line yet, for several reasons. One, the DUP has distrust and suspicions that promises made would be kept. The party doesn't want to be sold out further down the line.

"And one of the problems with giving the DUP a seat in any future trade talks, it still doesn't solve all the problems with the backstop.

"And it raises the question, over if the DUP get it, well would Wales and Scotland be able to demand that, too?"

BBC News Channel

Labour leader Jeremy Corbyn has already stressed his opposition to Theresa May's withdrawal agreement, which will be voted on in the Commons tomorrow.

But Prisons Minister Rory Stewart has made the case for why he thinks MPs from the party should back the vote, arguing it is about "stuff we agree on".

"They still all have the leverage over the other stuff, because we still have to take through the political declaration through a meaningful vote in Parliament," he said.

"This is like any disagreement - there's a bit we agree on, just make it simpler, break it down into chunks.

"Both Labour and the Conservatives back the withdrawal agreement, so let's get that done."

Labour leader Jeremy Corbyn and Prime Minister Theresa May spoke for 20 minutes on the phone this afternoon, according to a Labour Party spokesperson.

Mr Corbyn set out Labour's opposition to the prime minister separating the political declaration from the withdrawal agreement.

According to the spokesperson, Mr Corbyn made clear that Labour would not agree a "blindfold Brexit" to vote through Mrs May's "damaging deal", which he claimed would leave the next Tory party leader "free to rip up essential rights and protections and undermine jobs and living standards".

Brexiteer and Conservative MP Andrew Bridgen - who has twice voted against Mrs May's deal - said he does not think the withdrawal agreement will go through tomorrow.

"The fact that it's been separated from the political declaration is more dangerous," he said, speaking outside Parliament.

"The withdrawal agreement, without the political declaration, is a trap.

"There's almost no chance of getting out of the backstop ever without the political declaration being attached.

"It seems like a legal nightmare for the government to do this. If they've done it just to get round the speaker and make it a different vote, I think it may be counterproductive."

When asked about his hopes for the next party leader, Mr Bridgen added that he wanted a Brexiteer to take over the Brexit process.

He added: "Parliament is so fragile that I can't see us getting through the next six months without a general election. So what we need is a big name and an election winner to be heading up the party."

BBC Political Correspondent Vicki Young says the government are trying to take some of the bits out that people don't like with the hope of getting the prime minister's deal over the line.

The government is trying to say the future relationship can be sorted out later, and that the aim for now is simply to get Theresa May's deal passed through the Commons, she says.

Vicki Young says a government source has told her tomorrow is about "momentum", and that while they do not believe they will win the vote, the government's focus is on "bringing the number of MPs voting against the deal down".
