The Bush administration is bracing itself for the latest memoir by a former insider. Joe Wilson, a former ambassador, will this week reveal the name of the government official who "outed" his wife - revealing her identity as a CIA operative in apparent revenge for his role in proving the White House made false claims about Iraq's efforts to develop nuclear weapons.

But in what has increasingly becoming the habit during Mr Bush's presidency, Mr Wilson will not make his claims on television, at a press conference or even in a newspaper column but between the covers of a "must-read" book. His memoir, The Politics of Truth: Inside the Lies that Led to War and Betrayed My Wife's CIA Identity, is published tomorrow.
