I have an article in the BJR “Spies in The Observer” which riffs off Stephen Dorril’s excellent paper on the 1968 Soviet release of MI6 documents.
Lashmar, P. (2015) “Spies at The Observer”, British Journalism Review, Vol. 26 No 3 September 2015, pp 60-65.
My article is not online yet but the reference can be found here.
