Nicolas Sarkozy questioned over Bettencourt donations

Former French President Nicolas Sarkozy has been questioned over claims his 2007 election campaign received illegal donations from France's richest woman.

After a 12-hour grilling by a judge, Mr Sarkozy was declared a material witness - which means he is a suspect but has not been formally charged.

Mr Sarkozy, 57, denies accepting 150,000 euros (£120,600) from L'Oreal heiress Liliane Bettencourt - well above the 4,600 euros (£3,700) legal limit.
