Claude Gueant denies any wrongdoing, saying on RTL radio today: "Nothing in the case is proof of the crimes that I'm accused of."
An official for the financial prosecutor's office confirmed that Gueant has been given preliminary charges of money laundering and forgery. He spoke anonymously because he was not authorised to speak publicly.
Investigators suspect that a 500,000-euro (USD 545,000) sale of two 17th-century Flemish paintings by Gueant could be linked to illegal campaign funds.
