Theresa May faces a crunch cabinet meeting later when she will try to win colleagues’ support for a draft Brexit agreement between the UK and Brussels.
Senior ministers will gather at Downing Street at 14:00 GMT amid calls to reject the deal from senior Brexiteers and Remain supporters.
Some cabinet members have “deep reservations”, BBC political editor Laura Kuenssberg said.
The PM is continuing one-to-one briefings with ministers on the plans.
Meanwhile, ambassadors from the remaining 27 EU member states will discuss the agreement and the possibility of organising an emergency summit to agree it.
If this happens, the government will then face a battle to win Parliament’s backing, with some Tories vowing to vote against it and Northern Ireland’s Democratic Unionist Party (DUP) also expressing concern.
