Roy Sydney George Hattersley, Baron Hattersley (born 28 December 1932) is a British Labour politician, author and journalist from Sheffield. He served as Deputy Leader of the Labour Party from 1983 to 1992.
Roy Hattersley has been a socialist and Labour supporter from his youth, electioneering at the age of 12 for his local MP and city councillors, beginning in 1945. His own mother, Enid Hattersley, was a city councillor, and later, Lord Mayor of Sheffield (in 1981). Enid Hattersley kept the fact secret from her son (until he was in his 50s) that his father, who died an atheist, had been a Roman Catholic priest, Father Frederick Hattersley, and had renounced the Church to marry her.
He won a scholarship to Sheffield City Grammar School and went from there to study at the University of Hull. Having been accepted to read English at the University of Leeds, he was diverted into reading Economics when told by a Sheffield colleague of his mother that it was necessary for a political career.
At university Hattersley joined the Socialist Society (SocSoc) and was one of those responsible for changing its name to the "Labour Club" and affiliating it with the non-aligned International Union of Socialist Youth rather than the Soviet-backed International Union of Students. Hattersley became chairman of the new club and later treasurer, and he went on to chair the National Association of Labour Student Organisations. He also joined the executive of the IUSY.
