It was then rumoured that the real buyers of the house near the summit of Highgate West Hill, which enjoyed a brief turn in the limelight as the Fame Academy house in 2002, were construction tycoon Elena Baturina and her husband, Yuri Luzhkov, the former mayor of Moscow. The couple have repeatedly denied all such reports and have taken legal action against those who have suggested otherwise. No other names have ever emerged but the very rich are often extremely secretive.
