A 12-bedroom mansion in west London has been sold for a record £70m - making it the most expensive house in the world.
Mr Mittal already has a £9m home in London
Billionaire Indian-born steel magnate Lakshmi Mittal is the new owner of the property in Kensington Palace Gardens.
The mansion was formerly owned by the Formula One racing boss Bernie Eccleston and extensively renovated in the 1990s.
Many of the floors and pillars are said to be made of marble imported from the quarry used to construct the Taj Mahal.
The mansion is made up of a former Egyptian Embassy and a one-time annexe of the Russian Embassy knocked together.
It was extensively renovated in the 1990s by Iranian-born art collector and financier David Khalili.
Inside it has Turkish baths, a ballroom, an oak-panelled picture gallery and an jewelled basement pool and security is controlled by 65 state-of-the-art CCTV cameras.
Mittal, who owns LNM, the world's second-biggest steel producer, is thought to be worth £3.5bn.
He already owns a £9m house on Bishops Avenue in Highgate, north London.
A property which sold for £62.7m in Hong Kong in 1997, previously held the Guinness Book of Records title for the world's most expensive house.
