Saudi Arabian billionaire Prince Alwaleed bin Talal has said he will donate his $32bn (£20bn; €29bn) personal fortune to charity. The 60-year-old nephew of King Salman is one of the world's richest people. He said he had been inspired by the Gates Foundation, set up by Bill and Melinda Gates in 1997. The money would be used to "foster cultural understanding", "empower women", and "provide vital disaster relief", among other things, he said. Mr Gates praised the decision, calling it an "inspiration to all of us working in philanthropy around the world". Prince Alwaleed is at number 34 on the Forbes list of the world's richest people. He has stakes in Disney, 21st Century Fox, News Corp, Apple, GM, Twitter, and a string of hotel chains and luxury hotels, including New York's Plaza Hotel and the George V in Paris.
