PARIS (Reuters) - The European Union’s Brexit negotiator Michel Barnier said on Wednesday that he was trying his utmost to ensure there was a deal on Brexit, though he reiterated the Irish backstop could not be renegotiated.

“I am doing all I can,” Barnier told France Info radio.

British Prime Minister Theresa May on Tuesday offered lawmakers the chance to vote in two weeks for a potentially disorderly no-deal Brexit or to delay Britain’s exit from the European Union if her attempt to ratify a divorce agreement fails.
