The UK Government has played down hopes of a breakthrough

The British Government has played down hopes of a Brexit breakthrough after the UK Prime Minister said talks are "now in the endgame."

Theresa May is meeting her Cabinet ministers today – however she is not expected to present them with a draft Withdrawal Agreement.

The Irish border remains the main sticking point, with the warring factions within her party and the wider House of Commons continuing to threaten mutiny over the proposals.

Speaking at a banquet in London last night, Mrs May said the talks have been “immensely difficult.”

“We are working extremely hard through the night to make progress on the remaining issues in the Withdrawal Agreement – which are significant,” she said.

“Both sides want to reach an agreement but what we are negotiating is immensely difficult and I do not shy away from that.”

She also pledged not to compromise on the result of the referendum – or to accept a deal at any cost.

It comes after the Tánaiste Simon Coveney said there was "still clearly work to do between the two negotiations teams."

"I think we need to give them the time and space now to finish that job," he said.

"The sooner that can be done, I think, the better for everybody."
