London mayor urges Brexit delay to break divorce deal deadlock

London Mayor Sadiq Khan has urged Prime Minister Theresa May to delay Britain's departure from the European Union, warning time has run out to rework her withdrawal agreement.

"It's clear that we can't reach a meaningful deal that's agreed by parliament by March 29," Khan, from Britain's main opposition Labour Party, told AFP on Thursday.

"I'm hoping the prime minister sees sense and either extends the notice period for Article 50, or withdraws Article 50."
