King Abdullah's nephew on Forbes rich list

The nephew of Saudi Arabia's King Abdullah - Prince Alwaleed bin Talal - has once again made it onto the 2011 Forbes rich list.

The royal - who is the chairman of the Kingdom Holding Company (KHC) - was revealed to be the richest person in the Middle East when he was ranked 26th on Forbes magazine's annual global ranking of billionaires, with a fortune estimated at $19.6bn.

Along with KHC, the prince's wealth is also made up of his lavish jewellery collection, his stakes in Citigroup and a French port and his investments in companies in both Lebanon and Palestine.

His fortune also comes from his investment in an engineering consultancy business, worth almost $12 million, other business stakes worth $560 million, and property with a value of $3.18 billion.

The extravagant royal also has a deluxe collection of transportation vehicles, including the world's first private super jumbo jet.

Prince Alwaleed bin Talal is married to Princess Ameerah and the couple have four children Prince Khaled, Princess Reem, Prince Najem and Princess Mona.
