With great thanks to Tom Symonds for forwarding these files to me.
The following is the complete file in the National Archives, PREM 19/588, ‘SECURITY. Sir Peter Hayman: allegations against former public official of unnatural sexual proclivities; security aspects’, which was made public today. Hayman was a senior diplomat and member of the Paedophile Information Exchange who is also believed to have been Deputy Director of MI6. For reports on this, see those from the BBC, Sky News, Guardian Independent, Telegraph, Mail and Mirror.
I will post further links relating to Hayman later; for now, I would recommend strongly people read this collection of articles at the Spotlight blog. Also of great importance are the most recent articles from Exaro here, here and here.
