British billionaires lose big in rich list

Collectively, the 1,000 multi-millionaires in the list saw their wealth fall by 37 percent. They are worth 258 billion pounds, down from last year's record total of 413 billion pounds.

The annual list is based on identifiable wealth, including land, property and other items such as art, racehorses or significant shares in publicly quoted companies, but does not include bank accounts.

The full list of the richest 1,000 in Britain is released on Sunday.
