It will be 20 years, in August, since the untimely death of Diana, Princess of Wales, and we can expect an avalanche of remembering, and raking over, the event and the circumstances of her short life.

Most people who were around in 1997 can recall exactly how they learned about Diana’s sad death. It was a critical moment in public life and afterwards different people took varying views of the event. Conspiracy theories sprang up about the circumstances of the accident – and questioned whether it really was an accident. People took sides about many aspects of Diana’s life, her divorce from the Prince of Wales and the role played by the “other woman” – Camilla, now Duchess of Cornwall.
