The veteran broadcaster David Dimbleby has said a cross-party public commission should appoint the BBC chair, in the wake of Richard Sharp’s resignation after breaking rules over dealings with Boris Johnson – but ruled himself out of the running for the job.

Sharp resigned after being found to have breached public appointment rules for failing to declare a connection to a secret £800,000 loan for the UK’s former prime minister.
