A group of doctors which has been investigating the death of government scientist Dr David Kelly wrote to the Chief Coroner today calling for his inquest to be resumed and the suicide verdict re-examined.
In a letter to Judge Peter Thornton QC, they said there had been "deficiencies in legal processes" which meant Dr Kelly's inquest had never been formally closed, no final death certificate had been issued and no cause of death had been confirmed by a coroner.
Critics, including retired Torbay Hospital surgeon David Halpin, have long fought for an independent hearing into the circumstances surrounding the Ministry of Defence expert's death in July 2003.
In today's letter, the doctors also said that the first police officer at the scene of Dr Kelly's death had changed his account of how his body was positioned, bolstering claims that it had been moved.
Dr Kelly's body was found near his Oxfordshire home in 2003 shortly after he was identified as the source of a BBC report about the Government's dossier on Iraqi weapons of mass destruction.
The doctors, led by radiologist Stephen Frost, have long campaigned for a full inquiry into how Dr Kelly died.
