I was just thinking about the way the British constituiton works. I know that it is in the hands of the PM to decide when Parliament is to be dissolved and a GE is to be called. But if a majority in Parliament wanted a snap election yet the PM was refusing to call one, then couldn’t they just pass a bill declaring an early election, which would bypass the PM due to the principle of parliamentary supremacy?
Yes, if the government wants things done fast, it can generally make it happen! Now that the Fixed Term Parliaments Act has been repealed, the PM again has the power to call elections more or less unilaterally, so they won’t need to do something similar in future.
