It is the latest development in a complex affair involving the French football club Paris Saint-Germain, the state of Qatar, a lobbyist, a former French intelligence agent and accusations of illicit espionage. The lobbyist in question, Franco-Algerian businessman Tayeb Benabderrahmane, was arrested and detained for several months in Doha in 2020 after having obtained confidential information belonging to the PSG president Nasser al-Khelaifi. Tayeb Benabderrahmane was later able to leave Qatar after reportedly signing a secret agreement and handing over all the information he possessed. However, according to a document seen by Mediapart, the lobbyist had kept hold of some of the confidential information on the PSG boss and wanted to ask for 100 million euros from the emirate, who own PSG, in return for his silence. Tayeb Benabderrahmane, who faces separate allegations involving private and illicit investigations on behalf of the football club, denies all the claims. Yann Philippin reports.
