Sir Paul McCartney has written to the American President to ask him to support an organisation which is working to restore peace in the Middle East.

OneVoice has more than 650,000 followers and aims to end the conflict between Israel and Palestine.

Earlier this year the ex-Beatle officially joined OneVoice's international board of advisers, which includes Hollywood star Danny DeVito and ex-boxing legend Muhammad Ali.

McCartney hopes Obama will lend his political weight to OneVoice which is working towards making sure voices from the two states are heard and acted upon to a peaceful end.
