Previously secret evidence about the death of Iraq weapons expert Dr David Kelly suggests that he died as a result of a "self-inflicted injury".
A post-mortem report blamed blood loss after cuts to his left wrist, aided by a painkiller overdose and "silent" heart disease.
The report was published in Britain on Friday, as ministers sought to end speculation over his death.
Dr Kelly's body was found in woods close to his Oxfordshire home in 2003, after it was revealed he had provided the information for a BBC news story casting doubt on a government claim that Iraq had weapons of mass destruction capable of being fired within 45 minutes.
Instead of a coroner's inquest, then-Prime Minister Tony Blair asked Lord Hutton to conduct an investigation, which found Dr Kelly, 59, had died from blood loss after slashing his wrist with a knife.
Lord Hutton requested that the details of the post-mortem examination and toxicology results be classified for 70 years, to protect the privacy of the Kelly family.
But the Ministry of Justice said it was now releasing the details "in the interests of maintaining public confidence" in Lord Hutton's conclusions.
The BBC says the report backs Lord Hutton's verdict that he committed suicide.
