A multi-million-pound mansion on London's 'Billionaires' Row' is at the centre of the latest High Court challenge to new powers introduced under so-called 'McMafia laws'.Three properties in London - which are said to be worth around £80 million in total - were made subject to unexplained wealth orders (UWOs) last May following an application by the National Crime Agency (NCA).A UWO - a power brought into force in January 2018 under so-called McMafia laws, named after the BBC organised crime drama and the book which inspired it - allows the NCA to seize someone's assets if they believe the owner is a 'politically exposed person' and they are unable to explain the source of their wealth.It was reported by the BBC on Tuesday, following an investigation with Finance Uncovered and campaign group Transparency International, that one of the properties is currently occupied by Nurali Aliyev, grandson of former Kazakh president Nursultan Nazarbayev.That property in The Bishops Avenue in Hampstead, north London - often referred to as 'Billionaires' Row' - is reportedly a high-security mansion featuring an underground pool and a cinema. The other two London properties involved in the case are in Manresa Road, Chelsea and Denewood Road, Highgate.
