high-security mansion on one of London's most exclusive roads is the target of the UK's latest use of Unexplained Wealth Orders (UWOs).
The property, owned by companies based in tax havens, has been frozen, meaning it cannot be sold or disposed of, ahead of a court hearing on Tuesday.
Nurali Aliyev, grandson of Kazakhstan's former so-called president for life, is the occupier of the home, records show.
The property is so big it has an underground pool and a cinema.
The fate of the property, which cannot be identified for legal reasons, and two others linked to Mr Aliyev's family will be decided in a major court battle that begins at the High Court on Tuesday.
