Leaving the European Union

I am intrigued by the hon. Gentleman’s astonishment at how a Labour MP could possibly make promises to the electorate during a referendum. His colleague next to him, the hon. Member for East Lothian (Martin Whitfield), will know what I am talking about. Did the hon. Gentleman read the vow that Gordon Brown put on the front page of Scotland’s biggest national newspaper immediately before the 2014 referendum? That was clearly a case of an Opposition politician—a Labour politician—making promises about what would happen if, in a referendum, people did what he wanted them to do. Why is the hon. Gentleman so astonished about what a Labour politician might do in 2016, when his own party leader did it in 2014?
