Mr Ball was the chairman of the National Advisory Board for local authority higher education, which was then considering cuts at polytechnics and local education college nationwide.

Referring to a giant effigy which the students planned to burn that night instead of a Guy Fawkes, he responded: "Better men than I have been burnt in Oxford, and not in jest. I am glad that, if I am to be burnt, it is only an effigy and in jest.

Meanwhile I will continue with my work, which is not easy, not pleasant, but, I believe, not wrong."
