LONDON — Planning officials at Westminster council in London have ruled to reject plans by a media mogul to create the UK's most expensive flat. 

Ashley Tabor, who owns radio stations including Classic FM, applied to knock two properties in the luxury Knightsbridge Apartments together to create a £200 million penthouse flat complete with 10 bedrooms, a cinema, and a butler's pantry.

Officials ruled on Thursday that the proposed "amalgamation" of two flats would "result in the loss of a family-sized residential unit, which is contrary to the council's housing policy.

Tabor had hoped to create the apartment, which could have been worth around £200 million, after buying the flat adjoining his existing home earlier this year. The Knightsbridge Apartments is a luxury development near Harrod's in central London.

The most expensive UK flat on record is a triplex apartment in the One Hyde Park development, which sold for £140 million in 2014.
