There is a rumour going around Tory MPs that the party whips have spies near Sir Graham Brady’s office and are watching for people who visit to deliver their letters of no-confidence in Boris Johnson. Some less brave MPs have given their letters to other members to deliver.

Any MPs who are worried about this should know it’s now possible to email your letter into Sir Graham rather than delivering it in person. But that doesn’t have quite the same dramatic feel to it, I suppose.
