In relation to England, the Conservative Manifesto reiterates the policy of English votes for English laws.
Now that exclusively Scottish matters are decided by the Scottish Parliament in Edinburgh, exclusively English matters should be decided in Westminster without the votes of MPs sitting for Scottish constituencies who are not accountable to English voters. We will act to ensure that English laws are decided by English votes.
The problems with this proposal are well known. A Government might have a working majority on English issues but not on British issues, or vice-versa. There’s also the problem of working out what are ‘English Laws.’
The only consistent solution is an English Parliament and executive with defined powers, similar to the Scottish Parliament.
The Tories say nothing about the anomaly whereby Scottish MPs can be appointed as Ministers to Departments whose responsibilities do not include Scotland. Perhaps they plan to resolve this by not having any Scottish MPs.
