UK Prime Minister Theresa May delays Brexit vote

British Prime Minister Theresa May will head back to Brussels to seek to renegotiate the so-called Irish backstop element of her exit deal with the European Union, a junior minister says.

Ms May abruptly decided on Monday to pull a parliamentary vote on her Brexit deal, throwing Britain's plan to leave the EU up in the air on the eve of the vote, after repeated warnings from MPs she faced a rout.

"Theresa May has listened to colleagues and will head to Brussels to push back on the backstop," Nadhim Zahawi, a junior minister in the Department for Education, said on Twitter.
