Sultan of Swing

Sir David Butler pioneered the science of elections, transforming the way we analyse election results. In 1945, aged only twenty, Butler was the first to turn British constituency results into percentages, and thereby founded the science of psephology. Appearing as an expert on Britain's first TV election night in 1950, he promoted the idea of 'swing' to explain gains and losses to the public. Later, he invented the BBC's popular Swingometer, which is still used today. He has publicly analysed every British general election since the Second World War, and done more than anyone to transform TV coverage of elections, with a style that combined authority and showmanship with his phenomenal memory for facts and figures. First summoned by Churchill for polling advice when he was only twenty-five, David Butler got to know most of Britain's senior post-war politicians and has acted as a highly influential voice behind the scenes. He wrote dozens of books and taught scores of leading figures in politics and the media around the world, building a huge international reputation which regularly took him to America, Australia and India. Award-winning TV correspondent Michael Crick has known David Butler for forty years. In Sultan of Swing, based on interviews with Butler himself, his friends, family and colleagues, and with access to many previously unseen papers, Crick chronicles the long and energetic life of the greatest analyst of British elections - a story that weaves its way through post-war history with surprises, colour and humour.

Michael Crick is journalist, biographer and broadcaster. He is the political correspondent for Channel 4 News.
