Former French president Nicolas Sarkozy went on trial on Monday, on charges of having received millions of euros in illegal financing from Libya’s late strongman Moammar Gadhafi for his successful 2007 presidential bid.

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.

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.
