A brilliant book about political rivalries through the ages, from the prize-winning biographer and historian.

Benjamin Disraeli and William Gladstone. Edward Heath and Margaret Thatcher. Gordon Brown and Tony Blair. Personal rivalry is the very stuff of politics. The causes and controversies, the parties and technology may have changed over time but political conflict is still dramatised by the competition of ambitious individuals for the highest offices. Over the past two hundred years the size of the electorate has grown enormously and the means of reaching it transformed out of all recognition but human nature itself hasn't changed.

In his thought-provoking book John Campbell considers eight pairs of rivals and shows how their antagonism, which often evolved into outright loathing, has determined the course of political conflict. In each of his cases studies - Fox and Pitt, Castlereagh and Canning, Gladstone and Disraeli, Asquith and Lloyd George, Bevan and Gaitskell, Macmillan and Butler, Heath and Thatcher, Brown and Blair - he combines a vivid narrative with an authoritative assessment of the historical legacy that reveals how ideology is inextricably entwined with personality.
