French prosecutors have requested a seven-year jail sentence and a €300,000 fine for French former president Nicolas Sarkozy for allegedly taking millions of euros from late Libyan leader Moamer Kadhafi to help his 2007 election campaign.

Nicolas Sarkozy has been on trial since January on charges of “concealing the embezzlement of public funds, passive corruption, illegal campaign financing and criminal conspiracy with a view to committing a crime”.

Sarkozy, president from 2007-2012, denies the charges.

On the final day of the trail on Thursday, financial prosecutor Sebastien de La Touanne called for a seven-year sentence describing the accusations against Sarkozy and the 12 other defendants as “high-intensity corruption”.

“A very dark picture of a part of our republic has emerged,” he told the court.

Referring to Moamer Kadhafi, De La Touanne said Sarkozy had concluded “a Faustian corruption pact with one of the most unsavoury dictators of the past 30 years”.

Prosecutors also requested a five-year ban on Sarkozy running for office and exercising certain privileges.
