So you both switch to personal attack because you can not answer the facts.
Fact. Labour overwhelmingly voted for a referendum.
Fact. The electorate overwhelmingly wanted one, especially Labour's core voters in their heartland constituencies.

As you freely admitted Steve, Labour would have been "toast" had it refused to promise a referendum in its manifesto.
They were every bit as afraid of UKIP as the Tories were.

Labour is still as split as the Tories over Brexit, and also split over anti-Semitism even on its front bench (see today's news).
