There never was a Churchill from John of Marlborough down who had either morals or principles', so said Gladstone. From the First Duke of Marlborough - soldier of genius, restless empire-builder and cuckolder of Charles II - onwards, the Churchills have been politicians, gamblers and profligates, heroes and womanisers. THE CHURCHILLS is a richly layered portrait of an extraordinary set of men and women - grandly ambitious, regularly impecunious, impulsive, arrogant and brave. And towering above the Churchill clan is the figure of Winston - his failures and his triumphs shown in a new and revealing context - ultimately our 'greatest Briton'.
