HC Deb 11 July 1963 vol 680 c175W
Mr. W. Hamilton

asked the Lord Privy Seal on what date Her Majesty's Government first knew that Mr. Philby had passed on a warning to Messrs. Burgess and Maclean.

Mr. Heath

As I told the House on 8th July, it was shortly before Philby's disappearance on 23rd January, 1963, that he admitted that he had warned Maclean through Burgess. News of his admission reached Her Majesty's Government not long after it was made. This was the first admission by Philby of which we had knowledge and the first occasion on which we knew of this fact.
