Thousands of government papers have apparently gone missing from the UK National Archives. Declassified documents covering some of the most controversial episodes from Britain’s past, including the Falklands War, Northern Ireland’s Troubles and the now infamous Zinoviev Letter Affair were among the missing files, having been officially “misplaced while on loan” to government departments. Some have claimed this is evidence of a government cover-up, but the truth is probably more mundane.
