Forbes magazine has released its latest list of the richest people on the planet.

There is no change in the top positions with Carlos Slim Helu, Bill Gates and Warren Buffett maintaining their lead, in spite of the global economic uncertainties.

The 2012 Forbes list contains 1,226 billionaires with a total worth of $4.6 trillion (£2.9 trillion).

Japanese real estate king Yoshiaka Tsutsumi topped the first list in 1987 with a net worth of $20bn.

High value real estate transactions, ownership of luxury items, charity contributions, valuations of equity holdings in public and private firms, real estate assets and cash in the bank are factored in to determining the world's wealthiest people.

Britain's richest billionaire and the 78th richest person in the world is Gerald Cavendish Grosvenor.
