PM May's power under attack as Labour Party threatens general elections

Britain's opposition Labour Party wants a national election if Prime Minister Theresa May cannot win the support of parliament for her Brexit deal, its business spokeswoman said on Sunday.

Labour's leadership has not supported the idea of holding a second referendum on the final deal, but Rebecca Long-Bailey said it would respect any decision by party members at Labour's annual conference this week to back the idea.

"Our position is that we want to have a general election if Theresa May can't get the support of parliament or even her own party to push through whichever deal," she told Sky News.

"Although it is not our position policy-wise if members decide at this conference that they wanted to have a people's vote or a second referendum, of course, we would respect the membership."
