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.
Sarkozy, who was president from 2007-2012, has appealed against his jail term at La Santé prison, where he is will occupy a cell roughly measuring 9 sq m (95 sq ft) in the jail's isolation wing.
More than 100 people stood outside his villa in the exclusive 16th district of Paris, after his son Louis, 28, called on supporters for a show of support.
Another son, Pierre, called for a message of love - "nothing else, please".
