Moving to the backbenches, veteran Brexiteer Sir Bill Cash says voting for the withdrawal agreement would be like "political castration".
He criticised his own government, saying: "When you ask a difficult question you get no answer."
And after being heckled by other MPs, he adds: "If they are so blind that they do not want to listen to these points, it makes no difference to me."

Tory Brexiteer Nigel Evans says he will vote for the prime minister's withdrawal agreement "through gritted teeth".
“The only reason I’m voting for this deal today is because we then technically do leave the EU and it’s much more difficult then to go back into the EU," he tells the BBC's Victoria Derbyshire programme.
"My biggest fear is that we'll be trapped in the EU," he adds.

Conlduing his response, shadow solicitor general Nick Thomas-Symonds says: "We will never mortgage all our futures on the outcome of a Conservative Party leadership contest over which most members of this House have no control and have to sit back and watch.
"The [vote] is a shoddy gimmick from a desperate government that is trying to hide away from the reality that this House still needs to bring back a meaningful vote on both the withdrawal agreement and the political declaration."

The Met says it has "appropriate policing plans" in place and will be ready to react to "any incidents" or spontaneous demonstrations.
A spokesman said: "We will always provide a proportionate policing plan to balance the right to peaceful protest, while ensuring that disruption to communities is kept to a minimum.
"To date, protests have been largely peaceful and we have no intelligence at this time to suggest that will change."

The SNP's Joanna Cherry attacks Geoffrey Cox and the government.
She says: "What we have heard today from the attorney general is an attempt to dress up political shenanigans as legal certainty.
"[It is to] try to solve Tory political problems so they can usher in a right wing prime minister."
She also tells Tories shouting her down in the Commons that maybe they should “join the mob outside”, referring to protests planned in Parliament Square later.

The shadow solicitor general lists examples where Theresa May had said the two elements of her deal could not be “banked” without the other.
Nick Thomas-Symonds says that without knowing the intentions of the future relationship, it is a “blindfold Brexit”.
But, after Mrs May’s announcement she will resign after the withdrawal agreement is passed, he adds: “Rather than it just being a blindfold Brexit, it is being blindfolded, and led into a different room by a different Tory prime minister.”
"The chicanery of this government trying to separate them does them no credit whatsoever."
BBC Radio Scotland
Image source, ReutersThe Scottish Secretary has accused MPs of playing party politics in their refusal to support Theresa May's Brexit deal.
Speaking on the BBC's Good Morning Scotland programme, David Mundell said that the level of "politicking" by opposition parties over Brexit could not have been anticipated by the prime minister.
He said: "It's very, very disappointing that colleagues, that other parties haven't supported the deal.
"I think one thing that we hadn't anticipated was the level of politics that would be played with the deal.
"What I think she [the prime minister] couldn't factor in was the level of politicking by other parties.
"It's quite clear that throughout this process, Labour have pursued their outcome of getting a general election, bringing the government down, ahead of securing a deal in the national interest."
Victoria Derbyshire
Children's Minister Nadhim Zahawi says he believes the vote on the withdrawal agreement later "will be close" but he adds he has spoken to a number of Labour MPs in Leave constituencies who are considering backing it.
Urging MPs to support the deal he says all the Brexit options parliament voted on earlier this week would require a withdrawal agreement to be passed.
He tells the BBC's Victoria Derbyshire programme: “I think colleagues, especially on 29 March – which was supposed to be the day that we leave with an orderly Brexit - should think long and hard, why wouldn’t they vote for the withdrawal agreement?
"Because all the options for the future relationship are still on the table."

Parliament
Shadow solicitor general Nick Thomas-Symonds has started his response to the government.
He says: "This House secured a proper meaningful vote for a purpose - so it could make an informed judgement on future of this country.
"The point was not to know only the terms of withdrawal but what the future relationship will look like.
"To consider those two thing together is vital."

After taking multiple interventions, Mr Cox concludes: "The House can take a single decisive step today to afford certainty to the millions of people throughout this country who are waiting for it to have a short extension not prolonged that will bring
"There will be no further uncertainty.
"I urge the House to vote for this agreement."

An intervention from Labour's Hilary Benn asks about any further extension.
"If we get until 22 May, and in the week leading up to it we still have not agreed [a deal] are [the EU] not likely to say, 'I am sorry, you cannot have one because you did not take part in the European elections.
"Therefore defeating this [motion] will at least give us a chance to make that choice."
Geoffrey Cox says voting through the withdrawal agreement today was "the only right we have to an extension".
He added: "If we move into next week without securing it, then we take the chance [any extension] will be vetoed by the EU 27 leaders."
Tory former Attorney General Dominic Grieve also questions Mr Cox, saying if we asked the EU for a longer extension, it would be granted.
But Mr Cox replies: "I never knew he had a crystal ball."

The attorney general says the government "respects the process" that Parliament is going through with indicative votes to try and find a consensus for a future relationship with the EU.
Geoffrey Cox tells MPs this could form the second part of the deal, known as the political declaration, that is not being voted on today.
"Of course the government respects that process is continuing," he says.
"It accepts therefore that further steps will be necessary to approve the political decalartion in this House.
"This House will have to ratify not only the withdrawal agreement but also the political declaration, and so the government will give consideration as to precisely how the full package will be approved."
