The memoir, "Back from the Brink," is to be published next week. The leaks suggest Darling paints a portrait of a Labor government troubled by Prime Minister Tony Blair's bad relationship with his chancellor of the exchequer and of Darling's own problems with Brown when Brown succeeded Blair, The Independent reported Friday.
In the most highly publicized bit, Darling quotes Blair on his successor: "Dealing with GB is like having dental treatment with no anesthetic."
Brown, Darling and Jack Straw were the only people to serve continuously in the Cabinet from the overwhelming Labor victory in 1997 to its ouster by the Conservative-Liberal Democrat coalition three elections later in 2010. But the long Brown-Darling relationship was not a good one, Darling said.
Darling said he tried to convince Brown the country had to cut spending. Darling said he became so isolated in 2009 when Brown tried to fire him, his wife compared him to Nazi war criminal Rudolf Hess, who spent years in solitary confinement.
Atlantic Books released a statement saying the leaks "do not fully and fairly represent the author's views as expressed in the book."
