Lord Borwick, the fifth Baron of Baking Powder, is a mischevious soul. He likes coming up with “modest proposals” which, if passed into law, would change life utterly. The other day he was suggesting that car exhausts should pour their burnt gases into the car’s cab, rather than into the air intake of the one behind.

His latest idea is that the Chancellor should read the whole of the Finance Bill to the House of Commons, rather than merely making a political speech and sweeping out, leaving everyone else to pick the bones out of the new legislation. Jamie Borwick goes further: only those members who stayed the course while the Chancellor read through the Bill would be allowed to vote on it. Modest? That’s one way of putting it.
