Vladimir Putin has been accused of secretly grabbing an ultra-luxury £100 million palace on the edge of a cliff in occupied Crimea — complete with a private hospital, operating theatre, cryochamber and gold-plated bathroom fittings.

The sprawling complex, hidden at Cape Aya at the southern tip of the Black Sea peninsula, was originally built for ousted Ukrainian president Viktor Yanukovych.

It has since been transformed into what investigators describe as 'a huge palace' belonging to the Russian dictator, according to an investigation by the team of 'murdered' Kremlin foe Alexei Navalny.

The main house alone measures 96,875 square feet, with a second cliff-side building of nearly 53,820 square feet hidden beneath landscaped gardens.

There is a private promenade, pier, and artificial beach with white sand, while a new helipad sits higher up the slope.

The interiors, according to project documents and photographs, are lavish even by Putin's standards at his other palaces including Valdai - which he alleges Ukrainian drones tried to attack this week - and Gelendzhik, an even larger Black Sea cliff-top residence.

'The sheer excess of luxury starts to make one feel slightly nauseous,' said the Navalny team.

There are two 'royal bedrooms' in separate wings.

The main Putin bedroom alone measures 2,600 sq ft with a 538 sq ft bathroom.

The 'boudoir' is 'about the size of three standard two-room flats'.

'Using a golden ladder and holding a golden handrail, one can climb into a golden jacuzzi and, in a relaxed state, watch [Putin-controlled state TV's] Channel One.'

Bathroom fittings shaped like flowers cost the equivalent of £28,330 investigators say.

'For that amount you could buy a studio flat, for example in [Russian resort] Sochi.'

But the total cost of taps, toilet-paper holders and robe hooks is £104,000 in each of the main bathrooms.

There is a woman's bedroom, presumably for Putin's longtime lover Alina Kabaeva, 42, and bedrooms for their sons aged ten and six.

There is also an adjutant's room for Putin's Federal Protective Service flunky.
