Russia summons French envoy over its billionaire senator Kerimov's arrest

Kerimov is accused of hiding tens of millions of euros from tax authorities while buying a string of properties on the glitzy Riviera in France through intermediaries

Russian billionaire senator Suleyman Kerimov was charged on Thursday with tax fraud in Nice, hours after Moscow protested his arrest in the French Riviera resort.

Kerimov was detained upon arrival at the airport on Monday, where he faced two days of questioning over alleged tax evasion involving the purchase of luxury properties.

He has now been released under strict conditions including handing over his passport and posting bail of five million euros. He also faces restrictions on his movement, state prosecutor Jean-Michel Pretre said.

A source close to the probe told AFP that Kerimov was accused of hiding tens of millions of euros from tax authorities while buying a string of properties on the glitzy Riviera through intermediaries.

His detention prompted the Russian government to summon France's deputy ambassador and angry Russian MPs passed a resolution branding the arrest a violation of the 1961 Vienna Convention on Diplomatic Relations, urging Moscow to press for his release.

"The senator status and the fact that he is a Russian citizen is a guarantee that we will, of course, put in all possible efforts to defend his lawful interests," Kremlin spokesman Dmitry Peskov said.

He stressed that 51-year-old Kerimov holds a diplomatic passport, though he is not believed to have used it when he flew in to Nice on personal business Monday.

A spokesman for France's foreign ministry said earlier Kerimov enjoys immunity from prosecution "only for actions carried out in the exercise of his functions" and it would be "up to the judge hearing the case to decide" whether or not the allegations relate to his official role and are covered by immunity.

Listed by Forbes magazine as Russia's 21st richest person with an estimated net worth of $6.3 billion (5.4 billion euros), Kerimov made his fortune during the privatisations that followed the break-up of the Soviet Union.

A regular visitor to France's Cote d'Azur, he has owned stakes at various times in Russian energy, banking and mining giants such as Gazprom, Sberbank and potash producer Uralkali.
