The paperback of The Prime Minister’s Affair will be published (in gold!) on the 14th of September. The 14th is a day when important things happen. Handel finished ‘The Messiah’; Napoleon marched into Moscow; and Queen Elizabeth 2 died a year ago. And it was in September 1931 that Mac broke with Labour colleagues to form a government with the Conservatives and Liberals. Why? Was it just politics or was it a blackmail plot that drove him to turn his back on lifelong comrades?
