Saudi Prince Alwaleed bin Talal.

Saudi Arabia's outspoken member of the royal family, Prince Alwaleed Bin Talal, has called on authorities to create a sovereign wealth fund to help reduce the state's reliance on oil.

"What I'm asking for now in this open forum is to have an active sovereign wealth fund, and to put in it all the excess foreign exchange that you have, all the money you have…" Prince Alwaleed told reporters in the Saudi port city of Jeddah while visiting the construction site of Kingdom Tower.
