So, then: some seven in ten members of our panel of party activists are willing, if necessary, to see the Government leave the European Convention of Human Rights, say, or the Refugee Convention.  If that’s necessary to stop the small boats.  And just over one in five are not.

There’s not much to add – other than that the last figure is a significant minority.  Were Conservative MPs to divide in the lobbies in the same proportion, assuming that legislation to such ends were necessary, the Government would find it impossible to get it through the Commons.

Assuming, again, that the opposition parties voted against such proposals.  That’s enough assumptions for the time being.  The result stands for itself.  Only six per cent don’t know, and only four of those who completed the survey didn’t respond to this question.
