The Fixed Term Parliaments Act, to which you refer, was a short-term political fix by David Cameron. It had all sorts of holes in it from the outset, and its repeal was inevitable sooner or later. We’re now back to the traditional system, in place for centuries, in which the election date is in the gift of the Prime Minister as long as he can command a Parliamentary majority, and no Parliament can last more than 5 years.
What I don’t understand is the reason for your repeated references to this. Are you saying that repealing the Fixed Term Parliaments Act was a bad thing? If so, why?
