While Lib Dems want to bring back fixed-term parliaments scrapped by Tories, Labour has no apparent interest
If Rishi Sunak sounds tetchy when asked the question, it is nothing compared with the frustrations of many voters: when exactly will there be an election? And why, crucially, is it entirely up to him?
To give the short answer, this is just the way UK politics is.

To borrow a phrase sometimes used about jury trials, it is perhaps the worst system in the world, apart from all the other ones.
