PARIS (AP) — Former French President Nicolas Sarkozy will publish a book about his recent time behind bars, titled “Diary of a Prisoner,” on Dec. 10, his publisher Fayard announced Friday. The house is part of the media group controlled by conservative billionaire Vincent Bolloré.

Sarkozy trailed the release in a post on X, writing that in La Santé prison “the noise is, unfortunately, constant” and that “the inner life of man becomes stronger in prison.” He spent three weeks in detention there this autumn.

The former head of state, who governed France from 2007 to 2012, was convicted on Sept. 25 of participating in a criminal organization over alleged Libyan financing of his 2007 presidential campaign. He was released pending appeal on Nov. 10, and his appeal against the conviction is scheduled to be heard from March 16 to June 3.
