Breathtaking account of the prime minister and how he got to where he is. Johnson was very nervous about what this book would reveal, though Andrew Gimson is a friend and a sympathetic biographer. He doesn't skirt over the embarrassing or controversial in Johnson's life, including his marriages, affairs and gaffes, but always has an excuse on hand to explain away this behaviour. It's a decent charting of what seems like an inexorable rise to the pinnacle of public, elected life.
