Official Secrets Act and Espionage

Monday 8th December 2025 Lords Chamber

Commons Urgent Question

The following Answer to an Urgent Question was given in the House of Commons on Wednesday 3 December.

“I thank my honourable friend for securing this Urgent Question, following the deeply disappointing collapse of the prosecution case concerning two individuals charged under the Official Secrets Act 1911. The allegations were hugely concerning, and we recognise and share the public and parliamentary frustration about this outcome. The Government welcomed the Joint Committee on the National Security Strategy’s inquiry and the opportunity it provided for parliamentary scrutiny on this important matter, alongside the ongoing review led by the Intelligence and Security Committee.

I will take this opportunity to thank the Joint Committee on the National Security Strategy, under my honourable friend’s chairship, for its diligent and rapid work. The Government will now take the time to consider the committee’s conclusions and recommendations properly, in conjunction with partners referenced in the report, before responding within the two-month timeframe.

However, I am glad that the JCNSS’s report has reinforced two fundamental points that the Government have made throughout. First, and as the Government have been saying for several weeks, the report makes it clear that there was no evidence of attempts by any Minister, special adviser or senior official to interfere with the prosecution. The report states that it found no evidence of improper influence. Despite ongoing questions about a meeting of senior officials that took place on 1 September, chaired by the National Security Adviser, the report clarifies that there was no deliberate effort to obstruct the prosecution.

The first senior Treasury counsel had already made the judgment on the basis of the evidence that charges could not progress by 22 August, more than a week before the meeting took place. We have been consistent throughout on these points, which runs in sharp contrast to our critics, who initially criticised the Government for intervening in the case and then, when it became clear that that was nonsense, criticised us for not intervening in the case.

Secondly, the JCNSS report reinforces a fundamental point that I have made to this House previously: the root cause of the failure of this case was the outdated Official Secrets Act 1911, which predates the First World War. The 1911 Act created an unrealistic test by requiring the prosecution to prove that China was an enemy. The Law Commission had flagged the term ‘enemy’ as being deeply problematic as far back as 2017. The Government will continue to work tirelessly to ensure that we have the most effective structures and processes in place to support law enforcement partners in mitigating and prosecuting foreign espionage wherever we find it.

More importantly, the ongoing disinformation around the collapse of this case has been distracting from the most important issue that we should be focused on: how the Government can work across this House to ensure that Chinese espionage will never be successful in the United Kingdom. As the Prime Minister stated in his speech at the Lady Mayor’s banquet on Monday:

‘Protecting national security is our first duty and we will never waver from our efforts to keep the British people safe’.

That is why, on 18 November, I set out a significant number of measures that this Government are taking to counter the threat that China and other state actors pose to UK democracy and society. In line with the JCNSS report, the Government will continue to strengthen our processes and preparedness for future threats, ensuring that we leverage our new security legislation effectively”.

[Baroness Finn (Con)]

My Lords, the report from the Joint Committee on the National Security Strategy describes the handling of the Cash and Berry case as “shambolic” and highlights serious systemic failures and deficiencies. The report raises serious concerns about the ability of the Government to pursue those who want to undermine our security. The chair of the committee, a Labour MP, has urged the Government to show the public that they are confident in standing up to adversaries when required. Will the Minister commit to responding to and implementing the key recommendations of the report? Can she now confirm that the Government accept the conclusion of this report that there was clear evidence that China poses a threat to the UK’s national security?

[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.

[Lord Sikka (Lab)]

My Lords, labelling something an official secret is all too convenient a way for the Government to keep people in the dark. One example is BCCI, a bank that was forcibly closed in July 1991 but there has never been a full independent investigation. After five and a half years of legal battle, I obtained one document called the Sandstorm report. It shows that the Government were funding al-Qaeda and protecting arms smugglers, murderers and others. Will the Minister now ensure that the document is made publicly available and at least put in the Library of this House so that we can hold the Government to account? What is so secret about it? I have put it on the internet and everybody can see it. Why can the Government not release it?

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

My Lords, I usually practise for left-field questions but I was not ready for that one. I thank my noble friend for his question and I will reflect on what he says, but let us be clear: the clear responsibility of this Government, as for any Government, is national security, and we will never undermine that.

[Lord Macdonald of River Glaven (CB)]

My Lords, does the Minister recognise that the statements of the Deputy National Security Adviser in the recent Chinese espionage case provided ample and sufficient grounds for the prosecution of that case?

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

I put on record my thanks to the Deputy National Security Adviser. He is an exemplary professional and has provided evidence in line with government policy of the time and government policy today. We continue to work closely with him and we are very grateful for his work. Noble Lords will appreciate that I am not noble and learned, just noble. On that basis, given that I am not a lawyer, this is not something that I can comment on, but we were very disappointed to see the case not taken forward.
