BBC chairman Richard Sharp told the BBC’s World at One: “I take comfort from the fact that Martin Bashir is no longer here. I don’t take comfort yet from understanding why he was rehired. We will find that out.”Asked what he knew of Bashir’s rehiring, including whether due diligence was carried out, he said: “I actually don’t know, that is being examined by the executive and they will report to the board on that. “I want to see the facts.”
