Wharf Cable intends to screen a documentary on Princess Diana despite controversy over its contents in Britain. The Granada programme Diana - The Secrets Behind the Crash speculates that the princess was murdered in a royal family conspiracy. It alleges that the driver of the car in which the princess and companion Dodi Fayed were travelling at the time of the August 31 crash in Paris was a secret agent hired by the royal family to kill Diana. In Britain, the Treasury Solicitor's Office warned Independent Television against broadcasting comments by a former MI5 agent. The ex-agent, who is prevented from revealing any information obtained while working for security services, was dropped from the programme, which screened in Britain last night. Wharf Cable hopes to show the documentary 'as soon as we can', programme controller Musetta Wu Yung-hing said. 'Hong Kong is a free community and we would fight it if someone tried to stop the programme.'
