It must feel ever-so-depressingly like groundhog day for Rishi Sunak. This morning, the PM made his grand speech at London Tech Week – all psyched to talk about his favourite new topic, AI — and instead found himself once again answering questions about Boris Johnson.

In the event Q&A, Sunak launched a scathing attack on his vengeful predecessor in a bid to bat away accusations that he had meddled with the former PM’s honours list to secretly block peerages for staunch Johnson allies Nadine Dorries, Alok Sharma and Nigel Adams.
