The Fixed-term Parliaments Act (FTPA) Repeal (2022): In previous eras, a Prime Minister could call an election at will. Under the constraints of the FTPA era, and prior to its repeal, Prime Ministers struggled to command the Commons, forcing the executive to negotiate continuously to maintain authority.
