The explosive evidence in Diana Inquest: The British Cover-Up blows the lid on the events that took place in the 24 hours following the death of Princess Diana in 1997. Diana's body was subjected to two embalmings and two post-mortems - in both France and the UK - within that first 24 hour period. In disturbing new findings - based on documentary evidence withheld from the 2007-8 inquest jury - the book reveals that Princess Diana's UK post-mortem samples were switched prior to toxicology testing. This shocking action means that the testing was carried out on blood and other samples that did not come from Diana's body. The book is based on evidence heard at the inquest, but also draws heavily on documents from within the British police investigation - Operation Paget. These official documents were not made available to the jury at the London inquest. In particular, this volume shows that the jury - who were expected to reach a verdict on the cause of the deaths - were prevented from seeing the UK post-mortem and toxicology reports for both Princess Diana and Dodi Fayed. Out of 23 documents connected to the post-mortem of Princess Diana, the inquest jury got to see just 2, and they heard evidence from only 3 of 14 key witnesses. Another surprising revelation in this fourth volume of the Diana Inquest series is that Diana's pre-post-mortem embalming, conducted in the Paris hospital within hours of her death, was ordered by the royals in Balmoral. The evidence in The British Cover-Up also reveals that on 31 August 1997 the then royal coroner, John Burton, took illegal jurisdiction over Princess Diana's body. These volumes on the Diana Inquest are essential reading for anyone who wishes to understand the events surrounding the deaths of Princess Diana and Dodi Fayed resulting from the car crash in the Alma Tunnel on 31 August 1997. A leading UK QC, Michael Mansfield, who served throughout the six months of the London inquest, stated in 2010: "I have read all of the books that John Morgan has produced.... I have no doubt that the volumes written by him] will come to be regarded as the 'Magnum Opus' on the crash ... that resulted in the unlawful killing of Diana, Princess of Wales and Dodi Al Fayed and the cover-up that followed." Dodi's father, Mohamed Al Fayed has said: "I believe that John Morgan has done more to expose the facts of this case than the police in France and Britain."
