A South Pacific jungle tribe that worships Britain's Prince Philip as a god is planning a tremendous celebration to mark his 86th birthday this summer.

The people of Yaohnanen and surrounding villages believe the prince to be the son of an ancient spirit who inhabits a nearby mountain on the island of Tanna and have worshipped the royal for the past 50 years.

However, they only recently discovered that Philip's birthday falls on June 10 and are now preparing a spectacular feast to mark the occasion, which they hope the prince will attend as guest of honour.

Chief Jack Naiva, who believes himself to be around 80, told Britain's Daily Telegraph newspaper: "You must tell King Philip that I'm getting old and I want him to come and visit me before I die.

"If he can't come he could send us a something: a Land Rover, bags of rice or a little money."

Prince Philip is aware of his status within the tribe and has even sent them some signed photographs.

The tribe isn't fazed by the prince's growing age and even believe he could be immortal. If this proves not to be the case, they are considering elected Prince Charles or one of his sons, Princes William and Harry, to take Philip's place.
