The World at One - Andrew Boyle
Interviewed by Robin Day, author Andrew Boyle discusses his book, The Climate of Treason, a look at five British traitors who were Russian spies. Though he refuses to identify two of the men because of legal concerns, Boyle explains some of the reasons why it took so long to unmask Guy Burgess and Donald Maclean.
During World War Two, Andrew Boyle worked in Britain's military intelligence in the Far East. He came to write the Climate of Treason after some disgruntled former MI5 colleagues of Anthony Blunt decided to expose his treachery because he continued to enjoy a privileged life in the UK. Boyle chose to use codenames for the previously unidentified spies, referring to Blunt as 'Maurice'.
