Wilf Proudfoot stood as the Conservative candidate in the marginal West Yorkshire constituency of Brighouse and Spenborough, where he ousted the sitting Labour MP Colin Jackson by a majority of only 59 votes. The closure of the pirate radio stations is believed to have been a key issue in a number of marginal seats. Proudfoot himself lost his seat in the February 1974 general election. Thereafter he spent some time in the USA where he trained as a hypnotist in Los Angeles. He later established the Proudfoot School of Clinical Hypnotism and Psychotherapy based in Scarborough.
