Nicolas Sarkozy could face questioning in a raft of party financing and corruption cases when he leaves the Elyse next week and loses his presidential immunity. The outgoing president could soon be called for questioning - either as a witness or potentially as a suspect - in several corruption cases ... after leaving office on May 15. Judges are likely to want to summon him over an investigation into who ordered French intelligence to unlawfully seek to uncover the source of journalists working for Le Monde. France's intelligence chief is currently under investigation over the affair in which Le Monde exposed embarrassing links between Mr Sarkozy's government and Liliane Bettencourt, the l'Oral billionaire caught up in a tax evasion and illegal party financing inquiry. Mr Sarkozy is suspected of benefiting from brown envelopes of cash to help fund his 2007 campaign from Mrs Bettencourt and her late husband, Andr, 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. Another case in which Mr Sarkozy's name has cropped up is the so-called Karachi affair", a complex investigation into alleged kickbacks on arms contracts.
