Lakshmi Mittal tops the list for the fifth year in a row
The UK's super-rich have seen their wealth fall in the past year during the economic downturn, according to this year's Sunday Times Rich List.
The top 1,000 richest people in the country now have £258bn between them, it estimates - down from last year's record of £413bn.
Over the past 12 months the number of billionaires has fallen from 75 to 43.
Indian steel tycoon Lakshmi Mittal, and family, are top again with £10.8bn, down a huge 61% from 2008.
"Never in the 21-year history of the Rich List has the collective affluence of those who live and work in Britain fallen by so much," says BBC business correspondent Joe Lynam.
"The super-rich may be better placed to weather the worst recession in 30 years, but if this list is accurate it shows that none are immune from it."
