Westminster time is counted in scandals, resignations, rebellions, U-turns and leadership crises. All the things that aren’t good government age a regime. Keir Starmer has presided over a lot of woes in 18 months, making a young government look old.

The policies and personnel are different, but to the casual passing voter the sound of screaming and breaking crockery around Downing Street is familiar as a sign of a political problem family in residence.
