The Brexit process remains in deadlock as MPs struggle to find a consensus on the next steps.
The Commons failed to find a majority for a way forward after voting for eight different options on Wednesday.
And while some senior Brexiteers have moved towards supporting Theresa May’s deal, the MPs she relies on in the DUP have refused to alter their stance.
The PM won some support by saying she would resign ahead of the next round of EU negotiations if her deal passes.
This means she still may bring her plan back to the Commons this week for another vote – the so-called “meaningful vote three” – despite it already being defeated twice by large margins.
Mrs May’s close ally and former deputy Damian Green told BBC Radio 4’s Today programme that the prime minister will “take the path of soldiering on”.
But although the prime minister has won over the likes of former foreign secretary Boris Johnson, a number of hardcore Brexiteers are still refusing to vote for the deal.
Former Brexit secretary Dominic Raab said he still believed it is still possible to get concessions from the EU on the deal, but if the bloc does not move, there should be “sensible conversations” around no-deal.
And the vice-chairman of the backbench European Research Group, Steve Baker, has suggested he may resign the Conservative whip rather than vote for the deal.
What happened last night?
MPs voted to seize power of the Commons on Wednesday and put forward a series of options to take Brexit forward – including leaving without a deal, creating a customs union and backing a confirmatory referendum on any deal.
But after several hours of debate, none of the eight options emerged as a front runner among MPs.
Conservative MP Sir Oliver Letwin, who oversaw the unprecedented process of “indicative votes”, said the lack of a majority for any proposition was “disappointing”.
But he told the Today programme no “assumptions” should be made about the outcome of further indicative votes, which he believes should take place on Monday if the PM’s deal is not approved this week.
“It’s very difficult to translate from how people vote the first time, when they don’t know how other people are voting, to how they will vote when they can see how other people are voting under new circumstances,” he said.
Ahead of Wednesday’s debate, Mrs May told a meeting of Conservative backbenchers she would leave office earlier than planned if she won Parliament’s backing for her withdrawal agreement with the EU.
Mrs May told her MPs: “I have heard very clearly the mood of the parliamentary party. I know there is a desire for a new approach – and new leadership – in the second phase of the Brexit negotiations – and I won’t stand in the way of that.”
She told MPs she would resign as party leader after 22 May – the new Brexit date – but stay on as PM until a new leader is elected. However, Downing Street said it would be a “different ball game” if the deal was not passed.
Did it work?
Mrs May’s announcement that she would not lead the talks with Brussels over the future relationship between the UK an EU prompted a number of Tory opponents of her deal to signal their backing.
The BBC’s political editor Laura Kuenssberg says the controversy over the PM’s deal has been centred on the withdrawal agreement – or the first phase of Brexit – so for many Tory MPs, a reassurance that it won’t be Mrs May who leads that next phase is important.
But, she says, politics is a strange business, and rivalries and ambition may be part of many MPs’ calculations too.
Prominent Leave supporters such as Mr Johnson and former Tory leader Iain Duncan Smith said they now viewed prime minister’s deal as the least-worst option.
But Mrs May needs to win over 75 rebels to overturn the 149-vote rejection of her deal on 13 March.
And many, including prominent Brexiteer and leader of the European Research Group, Jacob Rees-Mogg, will not side with her unless she gets the support of the DUP – whose leader said on Wednesday they could not vote for the deal.
Mr Rees-Mogg told reporters: “I don’t think the deal’s suddenly got better, simply that the alternative is now worse.
“I’m in favour of the deal and I hope the DUP will come over to the deal, but we’ll have to wait and see what they do.”
The DUP’s main objection is to the backstop, the “insurance policy” designed to avoid the return of border checkpoints between Northern Ireland and the Republic of Ireland in the event a future trade deal is not agreed.
It argues that the measure would result in Northern Ireland having to abide by different trade rules to the rest of the UK, which leader Arlene Foster says would “damage the Union”.
“The backstop in that withdrawal agreement makes it impossible for us to sign up to the agreement,” she told the BBC.
Party colleague Jim Wells said no unionist would ever back Mrs May’s withdrawal agreement as it was, since it would leave Northern Ireland “sitting in the waiting room for constitutional change”.
Mr Raab said he wanted the government to go back to the EU again, to “keep the arm of friendship open” and “explain that there’s still time for an exchange of letters providing a legally binding exit from the backstop”.
He added: “A lot of people say the EU just won’t move. That’s been treated as a fixture of these negotiations rather than being tested.”
But, if not, Mr Raab called for conversations to “mitigate any potential damage” from leaving without a deal.
“If we do all of those things in the spirit of realism and pragmatism, we’ll find a way through,” he said.
