Former BBC director-general Lord Hall has resigned as chairman of the National Gallery saying continuing in the role "would be a distraction to an institution I care deeply about".
Lord Hall was the BBC's director of news and current affairs when Martin Bashir's explosive Panorama interview with Princess Diana was aired in 1995.
The former director-general was heavily criticised in the Dyson report for his botched inquiry into how Bashir secured the interview.
Lord Hall said in a statement on Saturday: "I have today resigned as chair of the National Gallery. I have always had a strong sense of public service and it is clear my continuing in the role would be a distraction to an institution I care deeply about. As I said two days ago, I am very sorry for the events of 25 years ago and I believe leadership means taking responsibility."
