A defiant Nicolas Sarkozy told a Paris court on Thursday that allegations of illegal Libyan financing of his successful 2007 presidential bid were a "conspiracy" and that not a single cent of Libyan cash would ever be found in his campaign.

The former French president has faced several legal cases since leaving office, but accusations that he received money for his 2007 election from Libyan authorities have been particularly damaging.

A trial has opened of France’s former President Nicolas Sarkozy and 11 co-defendants over alleged illegal financing of his 2007 presidential campaign by the government of then-Libyan leader Moammar Gadhafi.
