Griffiths was defeated by the actor and Labour candidate Andrew Faulds in the 1966 general election. Griffiths wrote his own account of his election in 1964. In "A Question of Colour" (1966), he asserted that he had "no colour prejudice". In the book he considered South Africa to be "a model of Parliamentary democracy" and that "Apartheid, if it could be separated from racialism, could well be an alternative to integration". Griffiths also blamed immigration from the Caribbean for the spread of disease.
