The trial over alleged Libyan financing of Nicolas Sarkozy's 2007 presidential campaign has revealed a web of intrigue and high-stakes diplomacy.

Central to the case is Béchir Saleh, a former aide to Muammar Gaddafi, who allegedly facilitated the transfer of millions of euros.

Saleh, now living in the Gulf, has refused to testify, citing safety concerns.

Prosecutors argue that Sarkozy's administration offered economic and political favors to Libya, including nuclear deals, in exchange for campaign funds.

The release of Bulgarian nurses from Libyan prisons and subsequent agreements with Gaddafi have raised further suspicions.

Sarkozy denies all allegations, maintaining his innocence throughout the trial.

The case continues to expose the murky intersections of politics and international relations.
