In 1952 Winston Churchill was entering the House of Commons when he heard a young Tory backbencher tearing into Labour’s Aneurin Bevan. ‘Who is that?’ Churchill asked the chief whip. ‘Iain Macleod, sir.’ ‘We must have him in the government,’ said Churchill. ‘I am afraid that he is too young to be eligible,’ was the chief whip’s reply. ‘On the contrary’, Churchill retorted, ‘he is too eligible to be too young.’ Macleod was 38, one year younger than David Cameron.
