HC Deb 12 February 1998 vol 306 c324W
Mr. Baker

To ask the Secretary of State for Foreign and Commonwealth Affairs if he will release for public scrutiny the files held by MI6 relating to the Zinoviev letter. [24746]

Mr. Robin Cook

[holding answer 26 January 1998]: The records of the Secret Intelligence Service are not released: they are retained under Section 3 (4) of the Public Records Act 1958. Having reviewed the arguments, I recognise that there is an overwhelmingly strong reason for this policy. When individuals or organisations co-operate with the service, they do so because an unshakeable commitment is given never to reveal their identities. This essential trust would be undermined by a perception that undertakings of confidentiality were honoured for only a limited duration. In many cases, the risk of retribution against individuals can extend beyond a single generation.

But I want to be as open as I can. The records of the SIS for the relevant period are incomplete, and offer an inconclusive picture on whether the Zinoviev letter was a forgery. But I have commissioned the FCO Historians to write a short memorandum, drawing on papers held by the SIS, as well as those in the FCO archives. When the memorandum has been prepared, I will write to the hon. Member and place a copy in the Libraries of the House.
