British Prime Minister Theresa May has said MPs faced a choice ahead of a vote on her Brexit deal: approving her deal or facing an exit with no deal or even the reversal of Brexit.

She said she was speaking to MPs about giving parliament a bigger role in whether the Irish backstop arrangement would be triggered, though she gave few details.

Mrs May said some in parliament were trying to frustrate Brexit and that she did not think another referendum on Brexit was the right course.

Speaking on BBC’s Radio 4 said: “There are three options: one is to leave the European Union with a deal… the other two are that we leave without a deal or that we have no Brexit at all.”

She added: “It’s clear that there are those in the House of Commons who want to frustrate Brexit … and overturn the vote of the British people and that’s not right.”
