May: UK needs clear stance on Brexit

Home Secretary Theresa May, the frontrunner in the contest to be Britain's next prime minister, said on Sunday the United Kingdom had to be clear about its negotiating stance on a post-Brexit deal with the European Union before triggering article 50.

Britons voted to leave the bloc in a referendum on June 23, prompting Prime Minister David Cameron to resign after he had led the campaign for a "Remain" vote.

Cameron has said his successor would have to decide when to trigger article 50, the formal step that will begin the process of negotiating the terms of Britain's exit.
