BBC: Saudi Arabia's Prince Alwaleed Bin Talal has accused Forbes magazine of understating his wealth.
In its 2013 list of the world's richest people, Forbes estimated Prince Alwaleed's net worth at $20bn (£13bn), putting him in 26th place.
However, the prince's office said the magazine used flawed valuation methods.
According to some reports, the prince estimates his net worth to be $29.6bn, a figure that would put him in the top 10 of the magazine's latest rich list.
The list, published on Monday, saw Mexico's Carlos Slim retain the top slot for the fourth straight year with a net worth of $73bn.
The 10th spot on the list went to Bernard Arnault and family of the luxury goods group LVMH, with a net worth of $29bn. » | Tuesday, March 05, 2013
