Liberal Democrat leader Sir Vince Cable tells the BBC that he will be backing the revocation of Article 50 to cancel Brexit, as well as backing a referendum with the option to remain in tonight's indicative votes.

He says the outcome of this "unprecedented situation" was unclear, but he that he expects two or three options to emerge as front-runners, including another referendum.

The prime minister bringing her deal back for a third time would "sabotage" MPs' efforts to find a solution to Brexit, "embitter relations even more" and Sir Vince says it would be likely to fail again.

He says that with Theresa May facing open revolt from her cabinet, "we've never had anything as damaging and divisive in our political history that I ever recall - even the Iraq War was a sort of vicar's tea party compared with what's going on at the moment."

He urges people to keep faith in the indicative vote process if it doesn't produce a clear answer immediately, stressing that it's only the beginning.

"We're trying to do in two or three days what the Government has failed to do in three years," he says.

Scotland questions in the House of Commons ends.

Theresa May will now take questions from MPs as Prime Minister's Questions begins.

This cross-party proposal calls for the current withdrawal agreement to be implemented, with the controversial "backstop" for the Irish border replaced by alternative arrangements.

It mirrors an amendment tabled by Tory grandee Sir Graham Brady in February - approved at the time by four votes - which authorised the PM to seek changes to the deal.

The idea came from an attempt to broker a truce between Conservative factions named after housing minister Kit Malthouse.

A former Conservative minister has called on Theresa May to give a "firm commitment" to standing down as party leader before the next stage of negotiations on leaving the EU.

John Whittingdale said he hoped the party would have a leader "who had been a supporter of Brexit" after the withdrawal agreement had been agreed and the UK begins discussions on its future relationship with the EU.

"If we could have a clear indication and firm commitment that when we open those negotiations in the second phase it will be under a new leader - then that would do a lot to confidence in the parliamentary party," he said.

Some have suggested Mrs May must name the date she will step down to have any hope of winning MPs' approval for her deal at the third attempt.

The PM has already told the party she will step down before the next general election.

Labour MP Stephen Kinnock says he'll be voting for a Norway-style arrangement with the EU.

"I've been completely consistent for the last two and a half years. I've been campaigning for what we now call Common Market 2.0 - some people call it the Norway option.

"It's respecting the referendum, without wrecking the British economy.

"We leave the political institutions, we leave the political project of the EU, but we keep a frictionless, very close trading relationship through the single market and a form of customs union."

Mr Kinnock insisted if MPs can agree a way forward on Brexit through indicative votes, the PM must deliver it.

The director of the official Leave campaign has written a blog in which he addresses the prospect of another referendum.

"Remember: we won last time even though the establishment had every force with power and money on their side," he says.

"They screwed it up because they do not have good models of effective action: they literally do not know what they are doing, as they have demonstrated to the world in the farcical negotiations.

"Beating them again and by more will be easier than 2016."

Concerning his non-appearance before the culture committee, he says the committee chair Damian Collins "faffed around for ages instead of agreeing a date".
