Theresa May has ruled out an early general election, but that has not stopped predictable calls for her to trigger one on the grounds that her elevation to the premiership without a general election is undemocratic. Robert Hazell suggests that in saying that an early general election is not necessary she is entirely correct: the idea that Prime Ministers need a personal mandate is a misunderstanding of our parliamentary system. Were she to want to hold an election it would not be impossible for her to do so, but the Fixed-term Parliaments Act makes this more complicated than it has historically been and, in the context of Brexit, it is unclear what an early election would resolve in any case.
Does a new Prime Minister need a democratic mandate?
As soon as it was announced that Theresa May would be elected unopposed in the second stage of the Tory leadership race, and so would become Prime Minister, the predictable cries went up that this was undemocratic. No one had voted for her, it was said, other than the 35,000 electors in Maidenhead who voted for her at the 2015 general election, and the 199 MPs who voted for her in the final ballot amongst Tory MPs. The 150,000 members of the Conservative party had been deprived of any choice in the matter, let alone the 46 million electors in the country at large.
Theresa May has herself ruled out the need for an early election. Constitutionally she is entirely correct: the idea that prime ministers need a personal mandate is based upon a fundamental misunderstanding of our parliamentary system. Only in presidential systems is the head of the government directly elected. In parliamentary systems we elect a parliament, not a government. Parliamentary elections are a two stage process: after we have elected a parliament, the new parliament then determines who forms the government. And it is not uncommon for the head of government to change part way through a parliament, and not to call a general election.That has happened five times since the Second World War: when Harold Macmillan succeeded Eden in 1957, when he in turn was replaced by Alec Douglas-Home in 1963, when James Callaghan succeeded Harold Wilson in 1975, when John Major followed Margaret Thatcher in 1990, and when Gordon Brown succeeded Tony Blair in 2007. So far as I can recall, only in the last case was it suggested that the new Prime Minister needed to call a second election.
