I have been playing a game with myself recently: asking just what would it take for me to vote Labour at the next election?

The gossip out of No. 10 has answered it for me: if, as rumoured, the Prime Minister toys with the idea of abolishing inheritance tax – at a time when the government has jacked up tax for many millions of workers through fiscal drag and lowering the 45 pence tax threshold – then suddenly Keir Starmer is going to look a relatively attractive option.
