William Hague has warned the Liberal Democrats that "It would be wrong to construct a government, which would not be stable [and] which would not have a Prime Minister elected by the people".
But the General Election was last Thursday.
Obviously, David Cameron has not been elected Prime Minister by the people at the General Election itself. If he had been, he would have been at Buckingham Palace and then at Downing Street with a Commons majority last Friday morning, in the way that Tony Blair was in 1997 and Margaret Thatcher was in 1979.
So certainly this morning Cameron remains unelected, and indeed not Prime Minister at all. So it is hard to see how he could fit Hague's criteria of "being elected by the people". If Cameron does eventually negotiate his way to Downing Street with the blessing of Nick Clegg and the Liberal Democrats, perhaps he too could legitimately be referred to as an unelected Prime Minister!
Cameron's party's share of the Parliamentary seats does give him a good chance of negotiating his way into power, as one of the possible and perhaps still most likely outcome of the general election fallout. And there is, as yet, little sense that he has given any thought to falling on his sword after falling short electorally of what his party expected, in case another leader could better conclude the negotiations!
Other Prime Ministers - Gordon Brown, John Major, James Callaghan, Alec Douglas-Home and Harold Macmillan - became Prime Minister without being directly elected, because we have a Parliamentary democracy. If the Conservatives believe this should be a directly elected post, that is an entirely new position which the party has never previously held in its history, and they ought to be proposing constitutional and electoral reform to achieve that.
Meanwhile, let us generously wish the unelected David Cameron well in his bid to be appointed Prime Minister in the next days or weeks.
