Alastair Campbell was born in Keighley, Yorkshire in 1957, the son of a vet. Having graduated from Cambridge University in modern languages, he went into journalism, principally with the Mirror Group. When Tony Blair became leader of the Labour Party, Campbell worked for him first as press secretary, then as official spokesman and director of communications and strategy from 1994 to 2003. He continued to act as an advisor to Mr Blair and the Labour Party, including during subsequent election campaigns. He now splits his time between writing, speaking, politics in Britain and overseas, consultancy and charity, as chairman of fundraising for Leukaemia and Lymphoma Research, and a leading ambassador for the mental health campaign Time to Change.

He lives in North London with his partner of thirty-five years, Fiona Millar. They have three children. His interests include running, cycling, bagpipes and Burnley Football Club. He has published six volumes of diaries, including the number one Sunday Times bestseller, The Blair Years, a memoir on depression, The Happy Depressive, and three novels.
