For years those within the Labour Party who are wholly opposed to Trident, for examplw, have accepted that this has been out of step with party policy. That hasn't stopped them working to win. Now it appears pretty clear that in fact they were in step with majority opinion in the grassroots party, andd those who disagree should do the same?

In Scotland the overwhelming mass of people are now opposed to Trident. There is no reason to assume that the people of English are irrevocably set in the other direction.
