On a hill by the Black Sea, near the Russian city of Gelendzhik, is the 18,000 square meter palace.
The images of the giant palace were widely spread when Alexei Navalny published a film on his Youtube channel just over a year ago.
The palace is said to have been built for President Vladimir Putin for a sum of just over SEK 11 billion, and the money must have come from corruption, according to Navalny.
Putin says he has nothing to do with the palace.
Private strip club and swimming pool
In the new video, the Navalny staff shows, among other things, a private strip club, a luxurious bathroom and a swimming pool.
Several pictures show the double-headed eagle - Russia's state emblem.
The announcement comes at a time when tensions are rising at the Russian-Ukrainian border.
On Friday, US and Russian foreign ministers also met for talks.
- It may be that you think this is a suitable opportunity to increase the pressure on the political leadership, says Carolina Vendil Pallin.
