PARIS: Former French president Nicolas Sarkozy may have mounting legal problems but his status as a top-selling author is not in doubt: his hastily written book about his recent prison experience has sold 100,000 copies in less than a week, according to his publisher.

The 70-year-old turned his three weeks behind bars in October-November into “Diary of a Prisoner” (“Le journal d’un prisonnier“) and has been on a nationwide tour to greet enthusiastic fans.

“’Diary of a Prisoner’ sold 98,610 copies in just a few days after its release in bookstores! A phenomenal number 1,” publisher Fayard wrote on social network X, citing sales figures from market research group NielsenIQ GfK.

The 216-page book recounts Sarkozy’s mundane struggles with noise and low-quality food, but has also made waves for its political message.

The former head of the right-wing Republicans party reveals a conversation with far-right leader Marine Le Pen and hints at a possible alliance between the traditional right-wing and Le Pen’s anti-immigration party.
