Police raided the headquarters of France’s far-right National Rally party Wednesday, in what officials said was an investigation into alleged fraud, illegal loans and forged documents relating to the party’s successful elections of recent years, writes NBC News.

It is the latest probe into whether the party has broken campaign financing laws, with its founder and de-facto leader Marine Le Pen being convicted of embezzlement in April and banned from office for five years.

On Wednesday, National Rally President Jordan Bardella wrote on X that 20 armed officers wearing bulletproof vests, accompanied by two judges, entered the party’s Paris offices and seized emails, documents and accounting records. He called it a “spectacular and unprecedented operation” that was “clearly part of a new harassment campaign”. he added, “It is a serious attack on pluralism and democratic change”.

Paris Deputy Prosecutor Charline Le Peutrec said the the raid was carried out to investigate whether the party financed elections in 2022 and 2024 using “illegal loans”, “overcharging for services”, or “fictitious invoices for services” that were subsequently claimed on official expenses.

No one has been charged, Le Peutrec said in an emailed statement to NBC News.

The searches were part of a wider investigation launched in July last year, the same date it launched a probe into Le Pen. The prosecutor’s office said Wednesday that the investigation related to “an unnamed person”. The far-right lodestar, who denies the offenses and is appealing, was convicted of hiring four fictitious assistants while she was a lawmaker in the European Parliament.
