On one thing, admirers and critics can agree. Tony Blair has been the most accomplished politician of his generation. A gifted communicator with an intuitive feel for the national mood, he has dominated Britain’s political landscape. Three consecutive election victories assure him a place in the history books as Labour’s most successful leader. Margaret Thatcher apart, no other prime minister since the Napoleonic wars can claim an uninterrupted decade in 10 Downing Street.
