This is an ideal John Murray book, dealing with historic personalities, with a narrative reinforced by family papers and an understanding deepened by family connection. Robert Lloyd George, the author, is the great-grandson of David Lloyd George, the prime minister. I hope it will be a best- seller, and can imagine it being un- wrapped, with real pleasure, from parcels beneath half the Christmas trees of Old England. What is surprising is that a book on this friendship has never been written before. David Lloyd George was the prime minister who won the first world war; Winston Churchill was the prime minister who won the second.

There are two views about the morality of political lying. The first is the classical British view that politicians should always tell the truth, as people should in private life. This view is usually qualified, as William Waldegrave qualified it before the Treasury and Civil Services Committee of the House of Commons: ‘In exceptional circumstances it is necessary to say something that is untrue to the House of Commons. The House of Commons understands that and accepts that.’ Such lies are only justified to protect a major public interest, where a refusal to answer would be taken as a confirmation of the fact, as in devaluation of the currency.
