In a magnificently researched new book titled No More Champagne: Churchill and His Money, David Lough, a retired banker who read history at Oxford University, recounts the unbelievable story of the former prime minister's fiscal excesses. After years of sifting patiently through Churchill's bank statements and bills, Lough, a skilled financial gumshoe, has amassed a trove of material that he deploys to great effect in his book.

We learn of Churchill's ruinous stock market speculation circa 1929 and the inheritances he squandered; his gambling rousts at the casinos in Biarritz and Monte Carlo; the thousands of pounds he sank into the upkeep of Chartwell, his beloved country mansion in Kent; and the unceasing torrent of cash he poured into maintaining a first-rate cellar.
