There has long been a habit of some English Conservatives for disregarding the interests of their Scottish colleagues. Many an English Tory will, when pushed, emit a snort when it is pointed out that some manoeuvre or other will not be popular with the Scottish Tories or that it overlooks the imperative to hold the Union together.

Scotland has devolution and its own distinct political set-up. The Scots cannot, runs the argument, expect to have all that and also exercise some kind of veto or have a disproportionately loud voice at the table in UK matters.
