MOSCOW: Billionaire and Vladimir Putin ally Arkady Rotenberg Saturday said he owns a Black Sea coast property that Kremlin critic Alexei Navalny says costs over $1.5 billion and belongs to the Russian president.

Navalny claims the 17,691 square metre mansion sits on a property 39 times the size of Monaco and features a casino along with a theatre, an underground hockey arena, an aquatic disco and a hookah lounge complete with a pole-dancing stage. Underscoring the grand price tag, Navalny noted in a two-hour video report that it features Italian-made toilet brushes estimated at 700 euros ($851) apiece.

Navalny's video has garnered over 100 million views on YouTube, helped spur the largest street protests in Russia in years and forced Putin to deny that he or his relatives own the property.
