London: Britain's Prince William has been named the world's most influential man in a survey, beating America's first Black President Barack Obama and the late Apple co-founder Steve Jobs.

The 29-year-old Duke of Cambridge also came ahead of British Prime Minister David Cameron, who secured last place in the list of Top 49 Most Influential Men, and micro-blogging website Facebook's founder Mark Zuckerberg.

Drew Lubega, UK editor of lifestyle site '', who commissioned the survey, said: "This was the year our readers believe Prince William finally came of age, making the Royal Family accessible and cool, in a way that the previous generation failed. He's a hard worker determined to use his global profile for good causes."

French DJ David Guetta came second in the list. Footballer Cristiano Ronaldo was third, journalist Piers
Morgan was fourth, and Obama came 10th in the poll of 7,200 men aged 18 to 40 years, a leading daily reported.

William has urged people to vote "for your favourite space for your community", which will be saved to mark the Queen's Diamond Jubilee.
