Vladimir Putin and the mystery owner of this palace

Villa Sellgren is built on an island in the Vyborg Bay, around 12 miles from the Russian border with Finland. Officially it belongs to close friends of the Kremlin but locals say it is the latest prestige home in a stunning property portfolio rumoured to be Putin's. 3D images supposedly highlighting the interior of the 16,150 sq ft Putin dacha show a grandiose indoor swimming pool, a steam sauna, a billiard room and study with the Russian double headed eagle emblem.
