In second place was Microsoft founder Bill Gates whose personal fortune stands at $56billion, although he has given away more than $30billion to charity.

And while he is as famous for his frugality as his empire of flat pack furniture, Ikea founder Ingvar Kamprad may have to tighten his belt a little further after losing three quarters of his $23billion fortune.
The 84-year-old saw his personal wealth tumble $17billion to just $6billion due to tax issues.
He has fallen 151 places on the list, down from 11th to 162nd place.
Just last month allegations came to light that Kamprad had been secretly running his empire via a foundation in Liechtenstein which supposedly helped his Swedish company avoid paying tax for years.
Nigerian sugar, flour and cement tycoon Aliko Dangote was this year's biggest riser, up 557% to $13.8bn. While Moscow overtook New York as the city with the most billionaires, including steel magnate Vladimir Lisin, right, worth $24bn
The claims jarred with his legendary reputation for frugality - he is known for driving a 15-year-old car, flying economy class and encouraging the thousands of staff in his global empire to use both sides of company notepaper when writing letters.
On the Forbes list he was the biggest loser but elsewhere there wasn't much movement.
Zuckerberg's wealth of $13.5 billion was up 238%, but the biggest gainer was Nigerian tycoon Aliko Dangote. The sugar, flour and cement magnate's worth grew 557 per cent, to $13.8billion, landing him at number 51.
Clare O’Connor, a reporter with Forbes' wealth team, said: ‘What is happening to the wealthiest people in the world gives a clue to the wider economy so when you see social media and commodities making big gains, it shows the way the wind is blowing.
‘The biggest loser has been Ingvar Kamprad because of financial issues. As part of the tax issues he has been facing he has stated he is no longer profiting from the Ikea business and is relying on his separate investment company so he has been downgraded.
The fortunes of IKEA founder Ingvar Kamprad fell the most, but he's still a billionaire
‘Moscow has replaced New York as the billionaire capital of the world and there has been a general movement towards developing countries and Asia.
‘The recession has not had a huge effect on those at the top either.
We are not back to the record levels of 2008 but things are creeping back up.’
