Mr Sarkozy is suspected of benefiting from brown envelopes of cash to help fund his 2007 campaign from Mrs Bettencourt and her late husband, André, whose former bookkeeper has told judges she withdrew 150,000 euros earmarked for Mr Sarkozy's then campaign treasurer. He also faces questioning over allegations he personally accepted cash from the Bettencourts during a visit shortly before his 2007 election. Mr Sarkozy denies wrongdoing on all accounts.
