Late-night UK-EU talks in Brussels ended with “optimism on both sides”, government sources say, although no final Brexit deal has been agreed.
The Northern Ireland border remains the key issue to be resolved.
Prime Minister Theresa May will update her cabinet on the latest developments at a meeting in Downing Street.
Addressing the Lord Mayor’s Banquet on Monday evening, the prime minister said the talks were “immensely difficult” but were now in the “endgame”.
No 10 says Mrs May will not have a new Brexit plan to put before the cabinet and will instead update them on the state of the negotiations, especially issues over how best to guarantee that there is no return to a visible border on the island of Ireland.
