Booker's weekly columns in "The Sunday Telegraph" covered a wide range of topics of public interest. He has been described by British columnist James Delingpole in "The Spectator" as doing "the kind of proper, old-school things that journalists hardly ever bother with in this new age of aggregation and flip bloggery: he digs, he makes the calls, he reads the small print, he takes up the cause of the little man and campaigns, he speaks truth to power without fear or favour".
