Britain's most expensive house goes on sale

A house in Belgrave Square is set to enter the record books with a price tag of £90million.

The six-storey stucco house in Belgravia, which is nearing the end of a two-year refurbishment, is one of the finest residences in a square dominated by embassies and offices.

Land Registry records show it is owned by a Madeira-registered company, believed to be run by a Lebanese man.

The owner paid £6.87million for a 99-year lease in January 2005.
