I did not vote to trigger article 50, but the point about hon. Members who are heckling me is that they do not like to hear that a massive betrayal is going on in the Labour party right now. The conference policy that was passed was to support a public vote, and nobody can explain to me why the Labour party has not got to the stage of supporting a public vote by now. All my hon. Friends in the Labour party know that by now we should have reached the stage of a public vote. So I appeal to Members across the House: now is the time to make a decision, to stand up for our constituents and do the right thing, for their livelihoods and jobs. We must support, this week, a public vote to put this issue back to the public, so that they can decide.
