Labour Party denies to support PM May raising concerns over Brexit

British Prime Minister Theresa May cannot expect the opposition Labour Party to save her in a parliamentary vote on any Brexit deal, Emily Thornberry, Labour's foreign affairs policy chief, said on Sunday.

"What we've said is that you cannot simply come to the House of Commons with a bit of nonsense ... you cannot expect the Labour Party to save you from your own backbenchers," Thornberry told the BBC's Andrew Marr Show, saying Labour would vote against any deal that did not meet its tests.

"If May loses the vote in parliament, Thornberry said: "The first stage is we demand a general election ... if we don't get a general election, then what we have said is all options remain on the table."
