Under English law, an inquest is required in cases of sudden or unexplained death. A French judicial investigation had already been carried out but the 6,000-page report was never published. On 6 January 2004, six years after Diana's death, an inquest into the crash opened in London held by Michael Burgess, the Coroner of the Queen's Household. The coroner asked the Metropolitan Police Commissioner, Sir John Stevens, to make inquiries in response to speculation that the deaths were not an accident. The police investigation reported its findings in Operation Paget in December 2006.
