West Ham owner says non-dom crackdown is driving wealthy from the UK

David Sullivan complains he is selling his six-storey house near Regent's Park at a loss as he reduces it to 65m

David Sullivan, the British businessman who co-owns West Ham United football club, has cut the asking price of his London house by 10m and has blamed the promised crackdown on non-doms for rich people leaving the country.

Sullivan, the chair and biggest single shareholder of the Premier League club, has reduced the price of his 21,000 sq ft town townhouse in Marylebone to 65m as he said he had to be realistic" about market conditions.

The six-storey house in Portland Place, an avenue near Regent's Park, has original Georgian features and a grand staircase in the entrance hall. It also has a wine cellar, two garages, a lift, an indoor pool and sauna, and a chef's kitchen. It went on the market last November.
