Forbes Richest Billionaires List Shows As Many Losers As Winners
Almost as many people on this year's Forbes list of the world's richest billionaires lost money as made money.
The biggest loser was Lakshmi Mittal, the Indian businessman who runs ArecelorMittal, the world's largest steel company.
Mittal, 61, lost around $10.4bn last year according to Forbes, putting him at a mere $20.7bn and outside the top 10 for the first time since 2004.
The world's richest billionaire, Mexican telecoms magnate Carlos Slim Helu, lost around $5bn.
Don't be too sad for him, however - he's still worth a total of more than $69bn.
Microsoft founder Bill Gates remained the second richest man in the world at $61bn, and investor Warren Buffett was third with $44bn.
Russian aluminium billionaire Oleg Deripaska lost almost half his fortune of $16bn last year, and accusations of criminal conspiracy saw Indians Shashi and Ravi Ruia lost $8.8bn, leaving them with a mere $7bn.
Other big losers including British author JK Rowling, whose fortune declined from more than $1bn to around $625m.
However Rowling's declining fortune was largely a result of charitable giving, since she gave away more than £100m last year according to Forbes.
Among the winners was Ricardo Salinas Pliego, the Mexican broadcaster, who earned an additional $9bn last year, putting him at $17.4bn.
Australian mining magnate Georgina Rinehart doubled her fortune from $9bn to $18bn after signing a deal with South Korean steel giant Posco.
The world's richest woman was named as Christy Walton, who given her estimated $25.3bn net worth might barely notice the $200m she received in Wal-Mart dividends over the past six months.
The richest man in the UK remained the Duke of Westminster, Gerald Cavendish Grosvenor, worth around $11bn. He dropped from 57th to 78th on the Forbes list but his overall net worth increased along with the London property market.
David and Simon Reuben were named the second richest in the UK with a combined $9bn, and third was Charles Cadogan with $4.6bn.
