Now one of the recipients of his outbursts has decided to strike back by painting a picture of New Labour's chief spin doctor as a bully who thought nothing of lying.
Campbell told a direct lie to Boulton, the political editor of Sky News, to steer him away from writing about a cabinet reshuffle. "'Sorry, Adam, you know why I had to tell you that,'" Boulton writes, of how he was told that Blair was at Chequers, rather than in No 10, a crucial detail for his story.
But Boulton says he was told an even more serious lie, by several people in the Labour party, during the 2001 election after Sky News broke the story that John Prescott had punched a voter. "Lord Falconer - a junior minister but operating as a counsel to the campaign - rang to warn me that I was making a grave personal mistake and was laying myself open to legal action," Boulton writes. "At the very time that Labour was officially denying the story and issuing naked threats, Campbell and co knew exactly what had happened and were consulting their lawyers."
