I don't expect voting to remain in the EU would lead to the issue dying, either. Even if Remain does win, it's not going to be decisive enough a win for that to happen, surely? Rather like in the Scottish referendum, reasonably close results tend to inspire the losers with more confidence, rather than less.
I've made no secret of my support for the Remain camp, but I don't care how narrow the margin is in favour of leaving. If the British people say we go, we should go. End of.
