Welsh author named as a spy
A file was kept on Welshman Goronwy Rees in the Kremlin
The Welsh author and academic Goronwy Rees has been named as a spy by the KGB defector Vasili Mitrokhin.
Until now there had been nothing more than suspicion that Rees was a Soviet agent.
BBC Wales reporter Sally Davies, who has been looking into the claims, said the Mitrokhin Archives revealed that Rees had two code names - Fleet and Gross.
He was regarded as a key element in Guy Burgess's recruitment strategy at Oxford University in the late 1930s.
"She said he was a minor player and not actually a spy because she always maintained that if he were a spy they would have a KGB file on him, well there now appears that there was."
The KGB regarded Rees as a useful contact because of his position as a fellow of All Souls Oxford where he would come into contact with top politicians.
But most commentaries suggest his communist sympathies were ideological rather than political.
He was recruited after writing an essay on mass unemployment in the South Wales Valleys.
But the archives confirm that Rees passed no information of any great importance to the Soviet regime - and that he ended his contact after three years because he was so sickened by the Nazi-Soviet pact.
However according to Mitrokhin, Guy Burgess wanted Rees assassinated because he was afraid of what he knew.
