Amazon CEO Jeff Bezos may be the world's richest man again

The battle for the title of'world's richest man' has taken a fresh twist. Amazon CEO Jeff Bezos, 53, may have pipped Bill Gates, 61, to the title after he added $6.5 billion (£5 billion) to his vast fortune yesterday. The jump came thanks to soaring Amazon share prices after its third quarterly earnings report beat expectations. Bezos now has a net worth of $90 billion (£69 billion), based on data from the Bloomberg Billionaire Index. Microsoft founder Gates still held the title at the market's close yesterday, with a net worth of $88 billion (£67 billion), according to the index.
