Brexit news - live: Three ministers resign as MPs vote to seize control over EU exit from May

Welcome to The Independent's live coverage of the day's political events, on what is set to be a big day in the Brexit process. 

Tory former minister Sir Oliver Letwin, who is leading plans for MPs to seize control of the Brexit process from the Government, acknowledged that the Commons may not unite around any of the available options.

Sir Oliver acknowledged that any votes would be advisory rather than binding on the Government and it may take several rounds of voting before a majority is found for any of the options - if one can be found at all.

He told BBC Radio 4's Today: 

 "[Theresa May] hasn't been able to get a majority and we don't know what she could get a majority for, so once we find that out there is a way forward, in principle, and then the next thing would be for the Prime Minister to take that forward and for the Government to implement it.

In case you missed it, reports emerged over the weekend that a coup was under way to oust Theresa May as prime minister. Michael Gove and David Lidington are the bookmakers' favourites to take the top job. 

Speaking on the Today programme, Tory backbencher Nigel Evans, a joint executive secretary of the influential Conservative 1922 Committee, said Theresa May should set out her plans to quit in order to get her Brexit deal through.

Clearly a number of people do not want the Prime Minister anywhere near the next phase of negotiations, which is the future trading relationship between ourselves and the EU."

Interesting development as Robert Peston, ITV's Political Editor, reports that Theresa May has told Brexiteers she will step down if they back her Brexit deal.

The Independent's Political Correspondent Ben Kentish understands cabinet ministers have been invited to view "new documents" this morning ahead of an emergency cabinet meeting. 

Here is what The Independent's Political Correspondent Ben Kentish has heard: 

Theresa May has summoned her cabinet for an emergency meeting at 10am this morning, where she is expected to set out plans to give MPs a series of "indicative votes" on how to proceed if they refuse to approve her Brexit deal.

No10 will put forward its own proposal in a bid to stop the Commons passing a backbench amendment that would pave they way for parliament to seize control and hold its own indicative votes on Wednesday.

Cabinet ministers have been invited to view new documents at 9am. These are rumoured to be the options that MPs will be asked to vote on, as well as new concessions on the backstop that are designed to win over the DUP's support.

Shadow attorney general Baroness Chakrabarti said a second referendum had never been Labour's preferred outcome.

Deputy Labour leader Tom Watson took part in the march of hundreds of thousands of people calling for a referendum at the weekend.

But Lady Chakrabarti told BBC Radio 4's Today:

It has never been our preference but since last autumn it has been one of a menu of options for breaking the deadlock.

And if that's what it takes to break a deadlock in Parliament then so be it.

I have no doubt that it will be one of a menu of options that MPs ought to be able to discuss and vote on this week."

She said Mr Watson was "an elected Member of Parliament so he is allowed to be rather more enthusiastic than me".

Asked about party leader Jeremy Corbyn's views, she said his job was to "desperately try to bring people together" from both sides of the Brexit divide.

Asked if Labour MPs would be given a free vote on the Brexit options, she said "we have to find a way to allow people to coalesce" but "we also are a democratic party and there was a conference motion last autumn and before that there was a general election manifesto" setting out party policy.

International trade minister, Liam Fox, is speaking on the Today programme and says there is a possibility the UK will crash out of the EU with no deal. 

He says it will "lead to a constitutional crisis" as parliament is not supportive of it.
