Saudi billionaire Prince Al-Waleed bin Talal has severed ties with the Forbes rich list after complaining that the publication significantly underestimated his wealth.
The Prince, who invested £300m (£198m) in Twitter in 2011, is listed as Forbes 26th richest man in the world with a net worth of $20bn (£13.2bn).
But, according to the Guardian, bin Talal informed the Forbes editor-in-chief that he would no longer provide the index with information about his finances because of the lists "flawed" methods.
Al-Waleed's own valuation of his wealth - $29.6bn (£19.5bn) - would rank him at number nine in the Forbes list.
Prince Al-Waleed bin Talal has given a rare interview to ITV News International Correspondent John Irvine.
The Saudi prince speaks of his hopes for President Obama's second term and his predictions for the future of Syria:
Prince Al-Waleed bin Talal has told ITV News that he would like to see further reform across the Middle East:
When asked if this included Saudi Arabia the prince replied: “All countries – no country is immune. Everyone who thinks he is immune, as you say in English, ‘he is talking rubbish’”.
Speaking to ITV News, Prince Al-Waleed bin Talal has predicted that Syrian president Bashar Assad will not flee Syria, and that the conflict with drag on for years.
He explained why Western powers are steering clear:
"Who are the insurgents, are they united? Are they extremists? Are they Al Qaeda based? Are they fanatics? Really, we don’t know who they are.
"They have groups there all over the place. That’s why the West, even Saudi Arabia, has not been very aggressive in supporting the insurgents over there."
