Peston published his biography of Gordon Brown, "Brown's Britain", in January 2005. It details the rivalry between Brown and the then Prime Minister Tony Blair. "Brown's Britain" was described by Sir Howard Davies, former director of the London School of Economics, as "a book of unusual political significance". The cover of the book describes how "Peston was given unprecedented access to Gordon Brown and his friends and colleagues." Having told Brown's side of the Blair/Brown power struggle, it is believed that Peston used the relationship then built up with Brown for many of his later financial news story "scoops" at the BBC.
