Timewatch (1982) : 5x1

Three films which reflect the way official records are preserved for future generations. Film 1: Christopher Andrew examines the extraordinary story of how the MS Automedon, entrusted with top secret documents, fell into enemy hands a year before the fall of Singapore and delivered to the Japanese priceless information which changed the course of the Second World War. Film 2: Peter Ibbotson reveals how the authorities decide which documents are thrown away and which are to be kept for future generations. Film 3: In a case which has parallels with modern phone-tapping scandals, Jeremy Black uses documents from Chancery Lane to show how the Foreign Office and the Post Office intercepted political mail in the early 18th century as Britain edged towards stable parliamentary democracy.
