Forbes has announced its list of the richest people in the world in 2010.

As a sign of the changing face of the world economy, just three of the top 10 on the list are from the US, with the rest coming from as far and wide as India and Brazil (and even one who lives in the UK).

Perhaps the biggest surprise is at the top of the list where Bill Gates, who has only been surpassed as the world's richest man once before since 1995, has been dethroned.
