Suella Braverman’s resignation letter is sensational – but this is no ‘Geoffrey Howe’ moment

Her departure was followed by a delayed explosion. Suella Braverman’s resignation letter was quite a bang: it is one of the most remarkable political documents ever published. The tone of fury is unmistakeable.

It recalls that other great act of revenge in resignation, of Sir Geoffrey Howe, who triggered the events that brought Margaret Thatcher down in 1990. He was a normally undemonstrative figure, who calmly launched an Exocet at his boss, releasing the pent-up anger of 11 years with quiet venom and deadly accuracy.

Braverman, on the other hand, is like an out-of-control punter starting a bar brawl with a broken bottle; she has been noisy and objectionable for some time, but has now gone into a rage.
