Amongst all the talk of overthrowing Gordon Brown the Tories have said that if Labour ‘forces another unelected Prime Minister’ on the country they’ll try and force an election. I’m not a constitutional expert, but two points stand out here:

1. Prime Ministers don’t have to be elected- they only need to be able to command a majority in the House of Commons

2. Related to 1, as long as any Labour Leader commands a majority in the Commons, how can the Tories win a vote of no confidence?

Now whilst it can be argued that the person of Prime Minister is integral to the identity of government (therefore favouring a poll every time that a new Prime Minister kisses hands) this argument is often made by the same people who decry the presidential nature of the premiership. In short, the critics can’t have it both ways.

Whether the public would wear another change of leader without a poll entirely depends on the circumstances: indeed, there were (Tory) people who said Gordon Brown shouldn’t hold a poll last autumn precisely because he would have won and this would have been a manipulation of the public sentiment. To sum up, there is no constitutional reason why there should be an election if the leadership changes: indeed, the only people who’ll be calling for one will be those who think they can win…
