When leaving a foreign posting, Britain"s ambassadors were encouraged to write a valedictory despatch until the practice was abolished in 2006. Unlike the usual style of the diplomatic bag, these last reports from foreign posts were unbuttoned, indiscreet and often very funny. There was much settling of scores, some poking fun of foreigners, a degree of moaning about the privations of Embassy life - and sometimes a bit of serious analysis too. Based on a very successful BBC radio series, Matthew Parris, who once worked for the Foreign Office and had the task of distributing the despatches, and Andrew Bryson have compiled an always entertaining and frequently hilarious volume of the best of them.
