Mexican billionaire Carlos Slim remained the richest person in the world with $74 billion in assets, while NRI steel magnate Lakshmi Mittal ranked sixth and Indian industrialist Mukesh Ambani is placed ninth in the US magazine Forbes annual list of world's top billionaires.
Telecom tycoon Helu, whose worth increased by $20.4 billion from last year's $53.5 billion, is followed by Microsoft founder and now a full time philanthropist William Gates III (popularly known as Bill Gates) with a net worth of $56 billion.
Investment guru Warren Buffet is at the third spot with assets worth $50 billion. Total number of billionaires, this year, has increased to a record 1,210 from 1,011 last year. Though America has the 33 per cent of the mega-rich, Asia-Pacific region has surged forward and overtook Europe for the first time.
Chairman of French luxury good outfit, Louis Vuitton Moet Hennessy (LVMH), Bernard Arnault has been placed at fourth spot.
With net worth of $41 billion, he is the richest person in Europe. He has replaced Ambani this year. Fifth place has been taken over by Larry Ellison of Oracle. The Oracle chief sits atop a fortune of $39.5 billion, which is $11.5 billion bigger than last year, thanks to a 30 per cent jump in his software company's shares.
Mittal ranked sixth with $31.1 billion of wealth. His wealth grew from $28.7 billion last year as his company ArcelorMittal, world's largest steel-maker, registered profits of $2.9 billion due to recovery in steel demand and higher margins in 2010, Forbes said.
Mukesh Ambani, with net asset of value $27 billion, lost five places and was placed at ninth position in this year's list.
Last year, Ambani held the fourth spot, with net asset of $29 billion, followed by Mittal at fifth place.
