Keith Allen screens Diana documentary

Keith Allen has been holding private screenings of his documentary There Are Dark Forces at the Cannes Film Festival.

The film, which examines conspiracy theories surrounding the death of Princess Diana and Dodi Al Fayed, allegedly includes footage of a young Prince Philip attending Nazi events.

It also contains secret camera recordings of members of the media discussing the circumstances surrounding the 1997 crash.

The screenings are reportedly being held in secret in a bid to prevent the Royal Family blocking the release of the film, which takes its title from words attributed to the Queen by the princess's former butler Paul Burrell.

It was recently reported that the documentary, co-funded by Mohamed Al Fayed, is unlikely to be screened in the UK.
