26 November 1969: The action was in protest against Britain’s involvement in Biafra, support of America in Vietnam, and against Cold Turkey slipping down the charts

John Lennon, the Beatle, has returned the MBE he was awarded – as were the other three Beatles – in the Birthday Honours of 1965.

Draft of John Lennon's protest letter to Queen Elizabeth found in record sleeve
A spokesman for Apple, the Beatle company, said yesterday that Lennon had sent identical letters addressed to the Queen, the Prime Minister, and the Central Chancery saying his action was “in protest against Britain’s involvement in the Nigeria-Biafra thing, against our support of America in Vietnam, and against Cold Turkey slipping down the charts.” The letter was signed “With love, John Lennon,” in his handwriting.

The spokesman added: “Typed underneath the signature is ‘John Lennon of Bag.’ The letters are written on notepaper headed Bag Production, 3 Savile Row, London W1.’ Bag is the company set up by Lennon and his wife, Yoko Ono, to handle the film Peace Events, records and other merchandise.”

Sir Derek Taylor, the Beatles’ spokesman, said that the other three Beatles did not know John was intending to return his MBE until after the letters had been sent. “They are not intending to return theirs as well.”
