Kim Philby
When fellow Labour MP Marcus Lipton used Parliamentary privilege to name Kim Philby as the 'third man' in the spy ring involving Guy Burgess and Donald Maclean, Daines was concerned. He intervened on a speech by Lipton in the House of Commons on 7 November 1955 to observe that what Lipton had done was "tantamount to a charge against that gentleman" and ask him for the source of his information. Lipton declined to respond, and Daines then raised a point of order insisting that Philby was unable to defend himself and that Lipton "owes it to the House to give the source of his information, or should withdraw the charge".
