Italian newspaper Corriere della Serra also reported that the French agent was acting on the express orders of Sarkozy.
"Since the beginning of NATO support for the revolution, strongly backed by the government of Nicolas Sarkozy, Gaddafi openly threatened to reveal details of his relationship with the former president of France, including the millions of dollars paid to finance his candidacy at the 2007 elections," the paper said.
The reports of involvement of French agents in the death of Gaddafi were corroborated by Mahmoud Jibril, who led the interim government in Libya after the ouster of Gaddafi.
Jibril told an Egyptian TV that "it was a foreign agent who mixed with the revolutionary brigades to kill Gaddafi."
The Daily Mail quoted diplomatic sources in Tripoli as saying "Sarkozy had every reason to try to silence the Colonel and as quickly as possible."
The new revelations said that Gaddafi had been tracked through his satellite telecommunications system as he talked to Syrian President Bashar Al-Assad.
