Prime Minister Theresa May said Britain would not flinch in an impasse with the European Union about its departure from the bloc, as French and German ministers suggested the next move in the negotiations should come from London.

British Prime Minister Theresa May on Friday demanded new proposals and respect from European Union leaders, saying after a summit in Austria that talks had hit an impasse and, in a prominent euroskeptic Sunday newspaper, she stuck to her guns.

"This is the moment to do what is right for Britain," May said in the Sunday Express. "Now is the time for cool heads. And it is a time to hold our nerve."
