What time is the Brexit ‘meaningful vote’ in Parliament on Tuesday and how long will the House of Commons debate last?
TODAY MPS will vote on the Brexit deal in what could be one of the most monumental Parliamentary decisions in more than 50 years.
But when exactly is this set to take place? Why did the Prime Minister delay the vote? Here's what we know so far.
When is the Parliamentary vote on Brexit?
Theresa May’s crunch Commons vote on her Brexit deal has been pencilled in for tonight, January 15.
MPs will begin voting at 7pm, but it is not clear what time the deal itself will be voted on because they will vote on the 14 amendments first.
The vote was initially scheduled for 7pm on December 11, but was cancelled by May at the eleventh hour.
On January 14, Mrs May was due to made a statement on the backstop - which could included new assurances from the EU.
The government was forced to start the process again by holding a full five days of debate running up to the vote, which began on January 9.
Many have cast this as the day of reckoning, when Britain faces the ultimatum of a new deal, or crashing out with a no-deal Brexit.
The PM dramatically abandoned the original ‘Meaningful Vote’ - after MPs had already debated it for three days in December 2018.
She took the unprecedented step after admitting she was on course to lose heavily.
What will MPs be voting on?
MPs will be voting on the withdrawal agreement that was approved by EU leaders on November 25, 2018.
Parliament has demanded that the Brexit treaty can only be ratified by the Government after it has been “approved by a resolution of the House of Commons on a motion moved by a minister of the crown”.
The vote will be a straight yes/no format, in a bid to make a decisive and "unequivocal" decision on the PM's deal.
It is expected that MPs will be able to vote on amended versions of the deal too.
Is the draft deal likely to succeed?
The outlook doesn't look good.
Theresa May has already had two Ministers resign over the deal, and her own Brexit Secretary, Dominic Raab, also quit as the draft deal was presented to Parliament.
Labour and factions within her own party have declared their intention to vote against it.
If the agreement is approved, what comes after that?
If Mrs May's withdrawal agreement makes it through the Parliamentary vote, it becomes a bill, which means even more voting.
This is arguably even harder, because MPs will have all the details, and every element will be under scrutiny - and up for another vote.
If the agreement is rejected, Labour has pledged to call a vote of no confidence in the Government in an effort to force a General Election.
Hardcore Eurosceptic Conservative MPs could also call a vote of no confidence in Mrs May as party leader if her deal fails to win approval.

What happens if the vote is lost?
The Prime Minister's Brexit plans suffered a blow in the run up to the debate on her deal when MPs wrestled back power from her.
First, around 20 Tories defied the Government and teamed up with Jeremy Corbyn to ban ministers from changing tax laws in a No Deal situation unless MPs openly vote for it, we get a deal passed, or Article 50 is delayed.
The plan was spearheaded by Labour's Yvette Cooper, Tory Nicky Morgan, Hilary Benn and Sir Oliver Letwin.
MPs then backed an amendment demanding the Government return within three sitting days with a new plan if it is defeated in vote on the Brexit deal.
The amendment, which was proposed by ex-Attorney General and Remainer in chief, Dominic Grieve, passed 308 to 297.
Meanwhile, some Cabinet ministers are planning for Britain to join an EU halfway house, EFTA, with the help of Labour rebels after giving up hope that the deal will pass.
Writing in The Sun, former Brexit Secretary Dominic Raab calls on the nation to “steel ourselves” to reject Theresa May’s Brexit deal and make the EU one final offer instead.
