Diana, Panorama and a BBC apology

Princess Diana's brother has called for an inquiry into the circumstances of his sister's historic Panorama interview.

The corporation said its investigation was "hampered at the moment" by the fact that Bashir was "seriously unwell" with complications from Covid-19. Amol Rajan discusses the allegations with BBC Royal correspondent, Jonny Dymond.

Also in the programme, why Substack has become one of the hottest brands in media, and a libel case loss for Johnny Depp.

Guests: Hamish McKenzie, co-founder of Substack, Vivian Schiller, executive director at the Aspen Institute, Persephone Bridgman Baker, senior associate at Carter Ruck, and Jonny Dymond, BBC Royal correspondent.
