French prosecutors on Wednesday requested a seven-year prison sentence for former president Nicolas Sarkozy in an appeal trial on charges that he sought Libyan financing for his 2007 election.

Sarkozy, France’s right-wing leader from 2007 to 2012, has always denied any wrongdoing but last year became modern France’s first former president to have gone to jail over the case, before he was released after 20 days pending his appeal trial.

Prosecutors had also requested seven years in the first trial over seeking to acquire funding from Muammar Gaddafi’s Libya for the campaign, as well as corruption, illegal campaign financing, and receiving misappropriated Libyan public funds.

A lower court sentenced him to five years only, over seeking to acquire the funding, but acquitted him of the three other charges.

In the latest trial, prosecutors called the former president an “instigator” of the alleged pact to receive funding to boost his campaign in exchange for help to restore the Libyan leader’s international image after Tripoli was blamed for two plane bombings.

Sarkozy told the court there was “not a single cent of Libyan money” in the campaign that saw him elected in 2007.
