UK and EU officials have agreed the draft text of a Brexit agreement after months of negotiations.
A cabinet source told the BBC that the document has been agreed at a technical level by officials from both sides after intensive discussions this week.
A special cabinet meeting will be held at 14:00 GMT on Wednesday as Theresa May seeks ministers’ backing.
The PM has been meeting ministers in Downing Street for one-to-one talks on the draft agreement.
BBC political editor Laura Kuenssberg said the agreement contained a UK-wide customs “backstop” aimed at preventing new border checks in Northern Ireland.
There is no additional Northern Ireland-only backstop – but sources wouldn’t be drawn on any specific arrangements for Northern Ireland on rules and regulation within the UK-wide one, she added.
This “backstop” has proved to the most contentious part of the withdrawal negotiations, with concerns raised by Brexiteer Tories and the DUP over how it will work.
