French ex-president Sarkozy begins jail sentence for campaign finance conspiracy

Nicolas Sarkozy has become the first French ex-president to go to jail, as he starts a five-year sentence for conspiring to fund his election campaign with money from late Libyan dictator Muammar Gaddafi.

Not since World War Two Nazi collaborationist leader Philippe Pétain was jailed for treason in 1945 has any French ex-leader gone behind bars.
