In brief
Nicolas Sarkozy has surrendered to La Santé prison to serve a five-year sentence after being convicted of conspiracy to fund his presidential campaign with money from Muammar Gaddafi's regime. Sarkozy maintains his innocence and continues to appeal the ruling. His arrival at the prison was met with public support, while he has expressed no fear of imprisonment.
Nicolas Sarkozy will 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 occupies a cell roughly measuring 9 sq m (95 sq ft) in the jail's isolation wing.
More than 100 people stood outside the jail, 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.
Nicolas Sarkozy, 70, was due to arrive at 10:00 (08:00 GMT) at the infamous 19th-Century prison in the Montparnasse district south of the River Seine. He continues to protest his innocence in the highly controversial Libyan money affair.
Sarkozy has said he wants no special treatment at the notorious La Santé prison, although he has been put in the isolation section for his own safety as other inmates are notorious drugs dealers or have been convicted for terror offenses.
Other than Philippe Pétain, the only other former French head of state to have been jailed was King Louis XVI before his execution in January 1793.
Inside his cell, he will have a toilet, shower, desk, and small TV. He will be allowed one hour a day for exercise, by himself.
At the end of last week, he was received at the Élysée Palace by President Emmanuel Macron, who told reporters on Monday it was normal that on a human level I should receive one of my predecessors in that context.
In a further measure of official support for the ex-president, Justice Minister Gérald Darmanin said he would go to visit him in prison as part of his role in ensuring Sarkozy's safety and the proper functioning of the jail.
I cannot be insensitive to a man's distress, he added.
Ahead of his arrival at La Santé prison, Sarkozy gave a series of media interviews, telling La Tribune: I'm not afraid of prison. I'll keep my head held high, including at the prison gates.
Sarkozy has always denied doing anything wrong in a case involving allegations that his 2007 presidential campaign was funded by millions of euros in Libyan cash.
The former centre-right leader was cleared of personally receiving the money but was convicted of criminal association with two close aides, Brice Hortefeux and Claude Guéant, to talk to the Libyans about secret campaign financing.
As he lodged an appeal, Sarkozy is still considered innocent but has been told he must go to jail in view of the exceptional seriousness of the facts.
Sarkozy said he would take two books with him into prison, a life of Jesus and the Count of Monte Christo, the story of a man wrongly imprisoned who escapes to wreak vengeance on his prosecutors.
