After studying history at Oxford and the University of Pennsylvania, Jonathan Powell worked for the BBC and Granada TV before joining the Foreign Office in 1979. In 1994 Mr Blair, then Leader of the Opposition, poached him to join his `kitchen cabinet' as his Chief of Staff. When Labour achieved its landslide victory in 1997 Powell was at the heart of the Downing Street machine. He was the only senior member of staff to remain at Blair's side throughout his time at the top of British politics. He has always maintained a low profile and has never before told his story.
