An Inconvenient Death - How The Establishment Covered Up The David Kelly Affair published by Head of Zeus is out on April 12, and Express.co.uk has been given a sneak preview. Dr Kelly's death came after he hit the headlines for letting slip to a journalist that Tony Blair’s claim that Saddam Hussein’s Iraq could deploy Weapons of Mass Destruction in 45 minutes was, at best, “dubious”. The 45 minutes claim was a major plank of the former Prime Minister’s argument to join the USA in an invasion of the country. The weapons expert had given evidence to the Foreign Affairs Committee just three days before on July 15 where he was asked about his alleged involvement in leaking information to BBC journalist Andrew Gilligan about the Government's so-called "dodgy dossier" arguing the case for war with Iraq being "sexed up". Dr Kelly had earlier been named in the press as Mr Gilligan's source, something the civil servant denied. Mr Goslett has probed events leading up to, and after, the 2003 death, which sparked a number of conspiracy theories including claims Dr Kelly was murdered by the intelligence services. There never was an inquest hearing because, the Government, instead ran the Hutton Inquiry which was set up to examine "the circumstances surrounding the death of Dr Kelly." The report, published in January 2004, concluded Dr Kelly took his own life, as a result of the stress he was facing around the disclosure of his name.

Earlier this week, Express.co.uk reported Mr Goslett's allegation that former Prime Minister Tony Blair ordered the setting up of the inquiry within minutes of learning the body had been found. But there has been much criticism that the inquiry circumvented the normal inquest process. A number of calls for the inquest to resume have been snubbed by different governments. Mr Goslett claims in the book that an inquest would have looked in a lot greater detail at the cause of death than the inquiry did, which looked at wider issues surrounding the run up to it. He also identifies 22 people or groups of people who he says were not called by Lord Hutton to give evidence at the inquiry, but should have been, in his opinion. He believes they should give evidence if an inquest ever resumes. Here, Express.co.uk looks at nine of the people and one couple and details the reasons why Mr Goslett claims their evidence is vital to the case, using some extracts from the book:

Mai Penderson said Dr Kelly struggled to slice a steak with his right hand. [YouTube]

1. Mai Penderson, a retired US Air Force officer who served as a translator with Dr Kelly's inspection team in Iraq in the 1990s. She told police Dr Kelly had a weak right hand after a 1991 horse-riding accident damaged his elbow. In spring 2003 she said she saw him struggle to cut steak with a knife in a restaurant, meaning she had "deep reservations" he could have used a pruning knife to cut his left wrist with that hand. She said he also struggled to swallow pills. Mr Goslett said Ms Penderson was called to give evidence, but did not after she was not allowed to do it anonymously.

2. Mystery policeman. DC Graham Coe told the inquiry he was with one other officer when they first saw the body. However, there were claims there were three policemen. Mr Goslett wrote: "Seven years later he admitted his existence to the Mail on Sunday." The author said an Oxfordshire businessman, Bruce Hay, who has since died once wrote to him saying the mystery man's initials were SB. He said: "Mr Hay said SB found the scene at Harrowdown Hill to be 'extraordinarily contrived'. Who is SB? What did he see? Why was he erased from the official account?"

3. Dr Bozena Kanas, Dr Kelly's dentist. On July 20 2003, she alerted police to an apparent break-in at her dental surgery, which must have occurred before it opened at 8am on July 18, the day Dr Kelly's body was found. Mr Goslett wrote: "It appears that Dr Kelly's dental records were removed in the break-in and were then replaced within forty-eight hours of Dr Kanas discovering this. "Although fingerprint tests showed six unidentified prints on the file holding the records, ACC Page of Thames Valley Police told the inquiry that no extraneous fingerprints were found."

4. The helicopter pilot and crew who flew over the spot Dr Kelly was found at six hours later with thermal imaging equipment. Mr Goslett said it detected nothing. He wrote: "The forensic pathologist determined the latest Kelly could have died was 1.15am, meaning that his body would still have been warm when the helicopter was looking for him. It was never raised at Hutton." 5. Sgt Simon Morris, one of three Thames Valley Police Officers who arrived at Mrs Kelly's house just before midnight on July 17 2003. It was in response to the missing person call. Morris anchored the initial search of the Kelly's house and the operation. Mr Goslett said: "despite this key role that night, he was not required to submit a written statement to Hutton and did not give oral evidence either."

Carne Ross said he was banned from discussing Dr David Kelly at the Chilcot Inquiry. [Twitter]

6. Carne Ross, a former British diplomat friend of Dr Kelly. Mr Gosl;ett said: "He had lunch with Dr Kelly in Nw York shortly before his death and was an occasional confidant. "Mr Ross was subsequently ordered by an official not to mention Dr Kelly when giving oral evidence to the Iraq inquiry conducted by Sir John Chilcot."

7. Nigel Cox, a friend of Dr Kelly. He who received an answerphone message from Dr Kelly arranging to meet him on July 23. Mr Goslett wrote: "He told me that police didn't listen to the message despite his offering it to them." 8. Sgt Alan Dadd, senior Thames Valley Police officer. He accompanied PCs Franklin and Sawyer to Harrowdown Hill and was therefore one of the first people to see Dr Kelly's body, however, was not called to give evidence, says Mr Goslett.

9. Judith Miller, a US journalist formerly with The New York Times and friend of Dr Kelly. Mr Goslett said: "He wrote an email to her on the day that he vanished saying that there were 'many dark actors playing games'. "What did this mean? And what else do the notes of Miller's peculiar interview of Janice Kelly, conducted on July 18 2003, show?"

10. John and Pamela Dabbs, who the Kellys stayed with less than a week before the death. "Mr Dabbs refused to disclose what they discussed. "Mr Dabbs is crucial in helping to define Dr Kelly's mood as he neared the end of his life. Both gave witness statements to Thames Valley Police."

Last week, Express.co.uk reported how Mr Goslett also claims a mystery new potential witness has said they would reveal new details about Dr David Kelly in the run up to his death if they were called to give evidence at a resumed inquest. Dr Kelly's body was exhumed last year at the request of the family, amid their concerns about campaigners, who are calling for an inquest to be opened, interfering with the grave. Mr Goslett concludes in his book that an inquest should still take place. He wrote: "It is clear that the Hutton Inquiry was an inadequate substitute for a coroner's inquest into Dr Kelly's death. "It raised more questions than it answered. "As a result of Tony Blair's decision to set up the Hutton Inquiry, the British public is required to accept that Dr Kelly took his own life. "But, based on the available evidence, there are too many inconsistencies attached to the official finding of suicide to accept it wholeheartedly.
