Senior Conservative backbenchers are expected to regroup today and decide whether to press ahead for changes to the party's rule book to enable an early leadership challenge to Theresa May.
It comes after MPs on the Tory 1922 Committee failed to reach a decision on Tuesday night amid growing pressure on the prime minister to name the date of her departure.
Ms May and Jeremy Corbyn have travelled to Belfast to attend the funeral of murdered journalist Lyra McKee, leaving the PM's deputy David Lidington and shadow foreign secretary Emily Thornberry to face off over Brexit and Northern Ireland at prime minister's questions.
During the session, Mr Lidington said both parties were making a "genuine attempt" to reach a solution to the Brexit impasse at Westminster, and said cross-party talks between negotiating teams hd been "constructive".
Ms Thornberry also used her remarks to urge the government to be "serious" about "putting the country first" by putting the option of a customs union - something Labour has demanded - on the table.
The shadow foreign secretary also criticised the forthcoming state visit by the US President Donald Trump, claiming: "The government is going to spend millions giving Donald Trump the red carpet, golden carriage treatment in June."

Theresa May has accused Labour of dragging its heels in the talks to find a Brexit compromise
On Tuesday, Theresa May accused Labour of dragging its heels in the bid to find a cross-party compromise to deliver Brexit.
“The discussions with Labour have been serious but had also been difficult in some areas, such as in relation to the timetable for the negotiations,” the prime minister told her cabinet.
No 10 fears Jeremy Corbyn does not share Ms May’s desire to avoid next month’s European parliament elections – which would require an agreement within days.
John Bercow under pressure to lift ban on Donald Trump giving speech in parliament
Hours after the US president's state visit was announced, Lord Fowler, the lord speaker, insisted "there is a strong case for a speech by the president particularly on such an important anniversary"Under current party rules, MPs cannot mount a fresh leadership challenge until 12 months after last December's failed attempt.
However, amid growing frustration over the latest delays to Brexit, some MPs now want to the rules to be rewritten to allow another challenge as early as June.
He told the BBC Radio 4 Today programme: "I think it would be quite wrong to say either the political crisis in Northern Ireland - the institutions having fallen over and not being put back up again, the essence of the Good Friday Agreement - nor Brexit caused this.
"The trouble with it is it's sitting out there as a political crisis and this sort of mindless violence can then fall into that."
"If we [the government] took stupid steps this could lead to a real crisis.
"I don't believe for a second the British government will do that, but the fact the political crisis is out there - both Brexit and the failure to put the institutions up again - is a real problem and that is a tinder for this kind of violence.
"This kind of violence is pointless by itself but it could affect this political wasteland out there, which is not really being addressed by the British government in a sufficient way."
Ann Widdecombe is standing as a candidate for Nigel Farage's Brexit Party
Former Tory minister Ann Widdecombe has declared she will stand as a candidate for Nigel Farage's Brexit Party in the upcoming European elections.
The 71-year-old will be the party's lead candidate for the South West in next month's polls, in an unexpected return to frontline politics after her retirement in 2010.
Ms Widdecombe said she felt "compelled" to return to the fray over her disgust at the handing of Brexit, and to allow the public to "fire a very loud warning shot across the bows of the parties they would normally support".

The Trump baby balloon will be back - and it could be even bigger
Anti-Trump activists have revealed the Donald Trump baby blimp will fly over London once again this summer in protest against the US president’s state visit to the UK.
The six-metre-high balloon – depicting Mr Trump as an orange, nappy-wearing infant – was first hoisted in Parliament Square during his visit to Britain last year and campaigners are hoping to stage even bigger demonstrations when he arrives in June.
Leo Murray, who helped crowdfund the blimp last year, and his fellow activists are reportedly “toying” with the idea of raising money for a baby hot air balloon about five times the size of the original balloon.
How the Tories can find their way out of the Brexit bedlam
Theresa May will allow Huawei to build key parts of the UK's new 5G network – despite fears the company will allow the Chinese government to spy on people using it.
The government is said to be satisfied that the company will only be allowed to build "non-core" parts of the infrastructure, such as antennas, keeping the information passed over it safe.
But politicians including Tom Tugendhat, the Conservative chairman of Britain's Foreign Affairs Committee, have criticised the decision, suggesting that it will make internet users in the UK unsafe.
Speaking at a TaxPayers' Alliance launch event in London, Mr Hancock said he still hoped there could be a majority in Parliament for a Brexit deal.
"Changing the Prime Minister will not change what we need to do to deliver Brexit, I think we should get on and deliver Brexit and I voted for that many times," he said.
"I hope the House of Commons will come to a majority to be able to deliver the result on the referendum."
