asked the Lord Privy Seal upon what date Her Majesty's Government first learned that Mr. Philby had moved behind the Iron Curtain; upon 103W what date Her Majesty's Government first learned that Mr. Philby was responsible for warning Messrs.

As I informed the House on 1st July, there is, as yet, no certainty about Mr. Philby's whereabouts. It would not be appropriate for me to give details of either the exact time or place at which various items of information bearing on the case were received by Her Majesty's Government. I am not aware104W of any association between Mr. Philby and Mr. Blake.
