"I currently have half a dozen Russian clients urgently looking to spend over 20 million each on buying a new home in central London. For them the address must be Belgravia, Knightsbridge, Mayfair or Regent's Park," said Gary Beauchamp.
Becky Fatemi, managing director of Rokstone estate agents, said the number of Russian clients on her books had doubled this year.
"There has been a big upturn in Russian buyers since the collapse of the ruble and the slowdown in the Russian economy due to international sanctions.
The Christmas season has not stopped them. Currently, I have several Russian clients looking to spend up to 100 million on a home in London."
Russian magnates are also leading the charge to snap up castles from hard-up Italian aristocrats. Across Italy, 70 privately owned castles and palaces, many in old Italian families for generations, are on the market, amid stories of Italian nobility selling off paintings to pay the bills.
According to the Florence-based Lionard Luxury Real Estate, Italy's nobles are setting their sights on super-rich foreign buyers, with 80 per cent of interest coming from Russian clients. The latest landmark to fall into foreign hands is the Castello di Tavolese. It was sold for between 10 million and 20 million.
In October, it emerged that a Russian buyer had bought one of the most glamorous villas on the Tuscan coast for 6 million.
