Paperback: Lloyd George and Churchill, by Richard Toye

Not only were these titans "the two most important figures in 20th-century British politics", but the uneasy link between them was "for both, their most important single political relationship". Tracing their bust-ups as fellow ministers during the First World War (Churchill's refusal to join Lloyd George's patriotic teetotalism is unsurprising), their alliance when cast from power and Churchill's adroit sidelining of Lloyd George during the Second World War, Toye's intelligent and assured book reveals that friendship and power do not mix.
