Silvio Berlusconi's decadent Sardinian villa that hosted infamous 'bunga bunga' parties and and welcomed several world leaders could soon have a new billionaire owner.

The sprawling Villa Certosa, once the crown jewel of the late Italian prime minister's vast property empire, is reportedly close to being snapped up by an unnamed Arab businessman for a staggering £432million.

This would make it the most expensive residential home ever sold, according to luxury property listings site Mansion Global.

The lavish 68-room estate, perched on Sardinia's glamorous Costa Smeralda, is no ordinary home. It comes with manicured gardens, terraces lined with medicinal plants, beds of exotic cacti, a faux stone tower, and even megalithic stone circles - which are, however, reported to be fake.

But its more outlandish features are what truly made it notorious. A monument to ostentation, the villa stuns any visitors with a mock volcano in its grounds, which at the flick of a switch emits the sound of eruption and sends fake lava cascading out of its cone. It once causing so much chaos that the local fire brigade had to be called in.
