Martin Bashir allegedly told Diana’s brother, Earl Spencer, that Charles was having an affair with William & Harry’s nanny, Tiggy Legge-Bourke, and this had resulted in a pregnancy which was terminated. This was one of the reasons which led to Diana taking part in Bashir’s Panorama interview.
The accusation caused Legge-Bourke great distress. “She felt she had to prove to others that the allegations were untrue by revealing highly sensitive matters, including private medical information”.
