A file of signals intelligence reports, messages, and correspondence issued by the Government Code and Cypher School and sent by the head ('C') of the Secret Intelligence Service (MI6) to the Prime Minister, Winston Churchill. This file contains a minute from C to the Prime Minister (PM) covering a signal from Roosevelt of January 19 concerning the Soviet press's reporting of alleged German/U.K. peace negotiations; from the Japanese minister in Madrid, a report of September 28 on rumours that Ribbentrop was to go to Spain in association with peace negotiations and rumours of a Soviet-German armistice; a report of November 4 on strong rumours that Ribbentrop and Von Papen had gone to Lisbon in association with Anglo-German peace talks - the minister considered there was no truth in these rumours; a report from the same minister on December 23 stating that he had met a Spanish marquis who claimed that he had personally arranged a car to take Ribbentrop from Biarritz to Lisbon, that Ribbentrop had arrived in Lisbon on November 11 to meet Churchill who failed to turn up, and that the British had allegedly earlier sent a letter to the Germans via German military quarters and Salazar to which they received no reply, so they felt unable to go ahead with the proposed meeting; from the Ministry of Foreign Affairs in Berlin, a press circular of January 18 on a Pravda report of German/U.K. peace negotiations - the Germans deny that there is any truth in the allegations and consider the Pravda article to represent a Soviet attempt to divert world attention away from the Polish Katyn affair; the PM's signal to Roosevelt of January 16 giving a suggested joint reply to Stalin's request for a share of the Italian Fleet; discussion on the communications channels to be used and the relevant U.K. and U.S. Sigint codewords of BONIFACE and MAGIC; and the Irish minister in Rome gives an account of the Italian internal situation, on December 21.
