Early General Election

I find this slightly perplexing. A lot of the Minister’s argument has been about the strong decisions of the Government in changing their mind, and about the ability of the Prime Minister to change her mind and take a different direction. He then makes exactly the opposite argument when it comes to Scotland and deciding the constitutional future of our nation. How can the Prime Minister and the UK Government change their mind in a matter of weeks, but the people of Scotland—despite every promise that was made eight years ago during the 2014 referendum campaign—are not allowed to make a different decision?
