Mrs May has previously asked MPs to vote on her deal – or aspects of her deal – on three separate occasions, with the Commons rejecting it heavily each time. Now the Prime Minister is believed to be planning a fourth vote, after MPs twice failed to give a majority vote to any alternative Brexit plan. However Mr Bercow, the Speaker of the House of Commons, has previously warned he would not allow a vote on her deal again unless it was substantially different to that voted on in the past weeks.
The BBC’s Laura Kuenssberg said on Twitter: “Whispers this morning that clerks in Commons have made it clear to govt that Bercow would not allow them to bring back the deal for another vote.
“One source says this is a ‘BIG PROBLEM’ – with capital letters – BUT Speaker’s office says not decided yet – let’s see.”
Theresa May is holding a marathon Cabinet session to try and break the Brexit deadlock.

The Prime Minister is gathering her top team for crisis talks in Downing Street after MPs again failed to find a majority for a series of alternatives to her Brexit deal.
A call for a customs union with the EU was rejected by just three votes, while a demand for a second referendum was defeated by 12 and a Norway-style deal put forward by Nick Boles by 21.
After a debate disrupted by semi-naked climate change protesters in the public gallery, “indicative votes” were again held in an attempt to establish what outcome might have majority support among MPs following a similar process last week.
MPs have control of proceedings in the Commons for a third time on Wednesday, but Speaker John Bercow said it was not yet clear what debates and votes will be staged.
The mastermind of the plan, Conservative former minister Sir Oliver Letwin, is expected to set out his proposals today.
Tory Brexit hardliners pressed the Prime Minister to now take a tougher line with Brussels.
The failure of any option to gain a majority in the Commons left the UK no clearer about its direction with the prospect of a no deal Brexit on April 12.
Brexit Secretary Stephen Barclay told MPs that if they wanted to secure a further delay from the European Union, the Government must be able to put forward a “credible proposition” as to what it would do.
But he held out the prospect of leaving with a deal next month – as long as MPs back one.
He said: “If the House were to agree a deal this week, it may still be possible to avoid holding European Parliamentary elections.”
