Daniel Finkelstein re: Andrea Leadsom standing for Tory Leader, and by default PM:
"There is nobody else who will have reached Downing Street without either holding very senior office or winning their own electoral mandate as leader of the opposition.
Here are the people who, in the last century, have come to office without first winning a general election: David Lloyd George, former chancellor; Andrew Bonar Law, former chancellor; Stanley Baldwin, former chancellor; Neville Chamberlain, former chancellor; Winston Churchill, former chancellor; Anthony Eden, former foreign secretary and deputy prime minister; Harold Macmillan, former chancellor and former foreign secretary; Sir Alec Douglas-Home, former foreign secretary; Jim Callaghan, former chancellor, home secretary and foreign secretary; John Major, former foreign secretary and chancellor; Gordon Brown, chancellor for a decade.
Contrast that list with: Andrea Leadsom, junior city minister and junior energy minister.
This is the first time that a prime minister will have been chosen by a group of party members. And Conservative Party members are entitled to choose who they like as their leader. It is important to emphasise that there would be nothing remotely illegitimate about a Leadsom leadership by itself. Personally I think it would be quite an odd thing to choose a complete novice at a time like this. A bit like saying: “For your first driving lesson how about trying a jumbo jet full of people.” But David Cameron resigned, after all, and if someone can win the contest under the rules then good luck to them".
