'Princes must got to Live8'

Bob Geldof has urged Princes William and Harry to support the Live8 show in London, after it was revealed that their father will not be attending.

The Prince of Wales, who was at the original 1985 Live Aid show with Princess Diana, has a "prior engagement" on 2 July.

Geldof says his sons must help put pressure on world leaders to ease poverty in Africa. He said: "William should be there. His mum was there for the original one and they should represent their generation."

William is set to be in New Zealand on official duty, while Harry is at Sandhurst military academy.
