"A Journey" gives a strong defense of his policies. One of the few Blair says he regrets is the ban on fox hunting, which caused outrage among many people in the countryside.
"I didn't feel how, for fox hunters, this was part of their way of life," he says. "The passions aroused by the issue were primeval."
In Britain, the book's most analyzed sections concern Blair's relationship with Gordon Brown, who was his partner in the Labour Party's 1990s modernization, served as Treasury chief and then succeeded Blair as prime minister. Brown was leader for three years before losing an election in May that brought a Conservative-Liberal Democrat coalition to power.
Blair says he felt that the prickly Brown "was going to be a disaster" as leader.
"Gordon is a strange guy," Blair writes _ "strong, capable and brilliant," but also "difficult, at times maddening."
"Political calculation, yes. Political feelings, no. Analytical intelligence, absolutely. Emotional intelligence, zero."
In contrast, former President George W. Bush is praised as intelligent, a friend and "a true idealist."
"I was asked recently which of the political leaders I had met had most integrity: I listed George near the top," Blair says.
Blair compares the fight against Islamist extremism to the Cold War and says the struggle in Afghanistan and elsewhere must go on for "as long as is necessary" _ possibly decades.
He calls the Guantanamo bay detention camp for terrorist suspects _ condemned by civil libertarians _ "a policy that was both understandable and, done in a different way, justifiable," although he says it was handled "almost in the most provocative way possible."
"A Journey" offers insights into the famous and powerful, including the observation that Nelson Mandela is not a saint and could be mischievous and blunt on occasion.
Blair said Mandela can be "as fly as hell when the occasion demands," using youthful slang to describe the elderly leader.
Blair recounts awkward interactions with the queen in the aftermath of Diana's death, when support for the British monarchy was at a low ebb. Blair said he tried to get the queen to make a public statement and worried that she found him "presumptuous." For his part, he said the queen "assumed a certain hauteur."
But the monarch had her domestic side. Blair recounts how during a weekend barbecue at the royal family's Balmoral estate _ "a vivid combination of the intriguing, the surreal and the utterly freaky" _ Prince Philip did the cooking while the queen donned rubber gloves and washed the dishes.
Diana was easier to get along with, an "extraordinarily captivating" woman. Blair says he warned her he had a bad feeling about her boyfriend, Dodi Fayed. "Dodi Fayed was a problem," he says, though he admits he was at a loss to say exactly why. "I felt uneasy."
Diana and Dodi were killed in a Paris car crash in August 1997. Blair's memorial speech, calling her the "people's princess," caught the public mood perfectly and helped cement his popularity at the time.
Elsewhere, Blair speaks of his relationship with alcohol, saying he drank a whisky or a gin and tonic before dinner, and a "couple of glasses of wine or even half a bottle with it."
"I had a limit," he says." But I was aware it had become a prop" _ though, on balance, he thinks booze did him more good than harm.
