With 37 days left to go until Britain leaves the EU, the Prime Minister will be joined by Attorney General Geoffrey Cox and Brexit Secretary Stephen Barclay as the trio seek to secure legally binding concessions on the backstop.
Tory Brexiteers have promised to vote down any deal Mrs May brings back from Europe that doesn’t include significant changes on the agreement’s major stickling point.
Mr Barclay and Mr Cox will lead afternoon talks with the EU’s chief negotiators before Mrs May meets European Commission President Jean-Claude Juncker this evening.
The Prime Minister is rumoured to be considering bringing forward the next meaningful vote on her deal in an attempt to see off pro-EU Conservative backbenchers who are threatening to join the newly formed Independent Group of MPs.
The vote is currently scheduled for February 27 but if Mrs May can secure the changes she needs there is hope the new deal could be signed off by European leaders this weekend at an EU-Arab summit in Egypt.
But at a Stuttgart press conference last night Mr Juncker warned: “There isn’t enough movement for me to be able to expect this to be a discussion with a concrete outcome.
“I don’t know what Mrs May will communicate to me tomorrow.”

8.11am update: Rees-Mogg’s Brexit backstop plan is ‘alive and kicing’
Jacob Rees-Mogg is adamant his Brexit plan to fix the disputed Irish border backstop mechanism is “alive and kicking”.
The European Research Group (ERG) chairman believes his so-called ‘Malthouse compromise’ is still being considered by Number 10.
Mr Rees-Mogg’s comment came after his pro-Brexit group held talks with Theresa May last night.
Backed by former Brexit minister and ERG deputy Steve Baker, the Malthouse Agreement would see Theresa May renegotiate the Northern Ireland backstop and replace it with a free-trade agreement and technology to avoid custom checks at the Northern Ireland border.
Following their talks with Mrs May, Mr Rees-Mogg and Mr Baker released a joint statement that said: “The Malthouse Compromise is alive and kicking.
“We look forward to further developments.”
