Only a week after the head of the BBC pledged never to broadcast again its discredited Panorama interview with Diana, Princess of Wales, it emerges that extracts from the 1995 program will be included in a documentary to be shown on Sky and Now TV next month.The Princess, a documentary directed by Ed Perkins re-telling the late Princess’s life through archive footage, will include footage of the interview, despite her son Prince William also expressing his wishes that this never be aired again. Perkins’ film has already had a brief run in UK cinemas.
