LONDON (Reuters) - Britain's wealthiest people saw their fortunes rise to record levels last year, according to the annual Sunday Times Rich List, at a time when most Britons' earnings and savings were squeezed by inflation and low interest rates.
Lakshmi Mittal retained his crown as Britain's richest man despite losing almost a quarter of his wealth over the past year following a fall in the share value of his ArcelorMittal, the world's largest steelmaker.
The combined wealth of Britain's 1,000 richest people swelled by almost five percent to more than 414 billion pounds, the highest recorded by the 24-year-old survey, the Sunday Times newspaper said in an advance release on Saturday.
Some 77 members of the 2012 rich list were billionaires, two more than the previous record in 2008.
Their good fortune contrasted with the economic plight of many Britons who face five years of austerity aimed at wiping out a record budget deficit as the economy struggles to recover from the 2008 financial crisis.
The three top places in the list were dominated by foreign-born magnates with a base in Britain who earned their fortunes from resource-based industries such as minerals, steel and oil.
Indian-born Mittal saw his personal worth slide by 4.8 billion pounds to 12.7 billion pounds, but that was still enough to keep him narrowly on top of the list.
Uzbek-born billionaire Alisher Usmanov, who owns around 30 percent of London soccer club Arsenal, was again in second place and close behind Mittal with a fortune of 12.3 billion pounds.
Russian investor Roman Abramovich, who owns rival London club Chelsea, held onto third place with a personal value of 9.5 billion pounds, down from 10.3 billion pounds last year.
The richest British-born billionaire was the Duke of Westminster, who slid from fourth to seventh place even though his largely property-based fortune rose five percent to 7.35 billion pounds.
Britain's richest woman was former "Miss UK" beauty queen Kirsty Bertarelli, who shares a 7.4 billion pounds fortune with her Swiss-Italian entrepreneur husband Ernesto.
The list was published as British Prime Minister David Cameron suffers a slump in his government's poll ratings following an unpopular budget last month that cut income tax for the richest earners.
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.
