Britain's opposition Labour Party will vote this week to keep a second Brexit referendum as an option if Prime Minister Theresa May fails to pass her plan to quit the European Union through Parliament, heaping pressure on a struggling leader.
But with the leadership intent on any such referendum not allowing a re-run of a 2016 vote to stay or leave the EU, the move could reignite tensions in the party, which, like much of Britain, is divided over how to quit the bloc.
After May's plans for Brexit — the biggest shift in British policy for more than four decades — were rebuffed by the EU last Thursday, the outcome of talks to leave are more uncertain than ever and have boosted those who want to stop the divorce.
