Lakshmi Mittal, the owner of steel producer ArcelorMittal and part-owner of Queens Park Rangers, who crowned the richest man in Britain in 2008, has lost more than £20bn ($28.81bn) since the financial crash.

He may have had £2bn wiped off his net worth in the past 12 months, but it's not all bad for the 65-year-old steel baron, who according to this year's Sunday Times Rich List is still the 11th wealthiest man in Britain, with £7.12bn in cash and assets.

Mittal is not the only member of the superrich finding himself in slightly straightened circumstances this year, either. Len Blavatnik, the owner of Warner Music, still made it into the list at number three with £11.59bn, but fell two places from last year's top spot after a £1.58bn dip in his fortunes in the last year.

Property tycoons David and Simon Reuben sat at the top of the money tree this year, after making a cool £3.4bn this year, capping their fortune at £13.1bn. The brothers own, amongst other juicy properties, London's Millbank Tower and the John Lewis headquarters, as well as London Oxford Airport and London Heliport. Sri and Gopi Hinduja, who run the Hinduja Group, are in second place once again this year, with their £13bn wealth unchanged.

Astonishingly, the number of London billionaires fell for the first time since the crash in 2008. There were 80 of them in 2015, compared with just 77 this year. A record 125 women made it into the top 1,000 list this time around – impressive if you consider that to get onto the list at all, a prospective entrepreneur would need a fortune of at least £103m.

Formula One's Lewis Hamilton is the wealthiest sportsman in Britain, with a net worth of £106m. Wayne Rooney doesn't make it onto the full list, but with £82m he was crowned the richest young sportsman in Britain. Sir Paul McCartney is the most minted musicians, with around £760m – a figure plumped by the £150m stake his American wife has in her family's business.
