Martin Bashir was a “serial liar on an industrial scale” and perpetrated “one of the biggest crimes in the history of broadcasting,” a former BBC boss has told MPs.

Former BBC director generals Lord Hall and Lord Birt appeared in front of the Digital, Culture, Media and Sport Committee (DCMS) today to give evidence on the BBC’s conduct surrounding Bashir’s now infamous 1995 Panorama interview with Diana, Princess of Wales.

Last month an independent probe by Lord Dyson found Bashir had been “deceitful” and commissioned fake documents to convince the princess she was being spied on, in what was a “serious breach” of the broadcaster’s guidelines.
