Official Secrets Act and Espionage

Baroness Tyler of Enfield Excerpts

Monday 8th December 2025 Lords Chamber

[Baroness in Waiting/Government Whip (Baroness Anderson of Stoke-on-Trent) (Lab)]

I thank the noble Baroness for her questions. I join her in thanking the Joint Committee on the National Security Strategy for its scrutiny and its work in shining some light—where there has been a great deal of heat—on what actually happened. On the key points that she has raised, we will reflect on the committee’s findings and I look forward to debating them with her across this Dispatch Box in due course when we come forward with our response to the report. I remind her of the Prime Minister’s comments at the Lady Mayor’s banquet last Monday about our position: China

“poses real national security threats to the United Kingdom … It’s time for a serious approach, to reject the simplistic binary choice. Neither golden age, nor ice age”.

He said:

“So our response will not be driven by fear, nor softened by illusion. It will be grounded in strength, clarity and sober realism”.

[Baroness Tyler of Enfield (LD)]

My Lords, rather than simply blaming outdated espionage laws, does the Minister agree with me, as a member of the Joint Committee, that, given the parallels in the new legislation, they will need to be carefully handled to prevent a similar outcome happening again? What assurances can she give that these lessons will be learned and acted upon? Is she able to cast any light on the fact that it took eight months for the second witness statement from the Deputy National Security Adviser to emerge—the reasons for which, the report of the committee said, were very obscure?

[Baroness Anderson of Stoke-on-Trent (Lab)]

I thank the noble Baroness for her work as a member of the committee. I make it clear that we keep all legislation and its effectiveness under review, and we will continue to do so under the new National Security Act 2023. I would like to reassure your Lordships’ House that one of the things we have already done was a change in the mechanism of government: the Security Minister now has joint responsibilities to the Home Office and the Cabinet Office, ensuring a level of co-ordination on some matters.

On her second point about timings, my understanding is that it did not take eight months on the government side. I will talk noble Lords briefly through the timeline: counterterrorism police first approached the Cabinet Office for discussions on the second witness statement on 25 November 2024, and the Cabinet Office then submitted the second witness statement on 21 February 2025. In the months between, the Deputy National Security Adviser was clarifying the request and working with a small number of officials from the National Security Secretariat, but our appreciation is that it was not eight months.
