Campaigning politician Norman Baker believes Dr Kelly, who exposed the Government's "sexed-up" Iraq dossier, was killed to stop him making further revelations about the lies that took Britain to war.
He says the murderers may have been anti-Saddam Iraqis, and suggests the crime was covered up by elements within the British establishment to prevent a diplomatic crisis.
The official Hutton Inquiry into the death of Dr Kelly ruled in 2004 that he slashed one of his wrists with a garden knife and took an overdose after being "outed" as the mole who revealed the flawed argument for invading Iraq.
But Norman Baker is convinced the scientist was murdered.
