Watch: A 'big moment' for France as Sarkozy jailed

Former French President Nicolas Sarkozy has begun serving a five-year jail term for using funds from late Libyan leader Muammar Gaddafi to finance his election campaign. Sarkozy, who served as president from 2007-2012, is appealing his sentence and is housed in a cell in La Santé prison's isolation wing. The incarceration marks a significant moment for France, according to BBC's Paris Correspondent Hugh Scofield.
