The PM’s hopes of extracting concessions on the Irish backstop are thwarted by EU leaders ruling out any renegotiation.

Theresa May is facing rival cabinet calls for a second EU referendum or a no-deal Brexit after returning from Brussels empty-handed.

The prime minister was hoping to extract concessions on the Irish backstop – the mechanism to prevent a hard border between Northern Ireland and the Republic.

But EU leaders made it clear there would be no renegotiation of her withdrawal agreement, making it all but impossible for Mrs May to get it through the House of Commons.

The majority of the cabinet now believe her deal to be “dead”, it has been reported.
