Official Secrets Act and Espionage

Matt Western Excerpts

Wednesday 3rd December 2025 Commons Chamber

[Matt Western (Warwick and Leamington) (Lab)]

(Urgent Question): To ask the Chancellor of the Duchy of Lancaster if he will make a statement on espionage cases and the Official Secrets Act.

[The Minister for Security (Dan Jarvis)]

I thank my hon. 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 hon. 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—

[Madam Deputy Speaker (Caroline Nokes)]

Order. The Minister will know that he should have restricted himself to three minutes for his response. That appears to have been four and a quarter minutes.

[Matt Western]

I thank the Minister for his comments, and I thank Mr Speaker for granting this urgent question demonstrating the importance of parliamentary security, safety and sovereignty. The case of alleged spying on behalf of China caused widespread concern among the public and Members of both Houses. My Committee, which is comprised of senior Members of both Houses, examined the timeline, and actions and decisions of the Government and the Crown Prosecution Service. While this was a highly unusual inquiry for a Committee to conduct, it was essential that Parliament examined the processes that led to the collapse of the case.

Our inquiry found nothing to suggest a co-ordinated, high-level effort to collapse the prosecution, nor deliberate efforts to obstruct or circumvent constitutional safeguards. However, we did find a process that is beset by confusion and misaligned expectations, and that can, at points, be best described as shambolic. There were systemic failures, and deficiencies in communication, co-ordination and decision making between the Crown Prosecution Service and the Government. Indeed, the episode reflects poorly on the otherwise commendable efforts of public servants to keep our country safe.

Given the conclusions I have just set out, will the Minister give reassurances that the Government will work closely with the CPS to ensure that communications and processes are tightened up, particularly when dealing with cases involving national security? Does the Minister acknowledge that the new National Security Act 2023, while comprehensive, may not entirely cover low-level espionage activity, especially given its structural parallels with the previous legislation? Finally, does the Minister agree that greater support should be given to the deputy National Security Adviser and civil servants acting as witnesses in such cases, to ensure top-level grip on cases with significant public exposure?

[Dan Jarvis]

As Mr Speaker has rightly acknowledged, these issues require a great deal of scrutiny from Parliament, and the Government are grateful for the opportunity to engage and work closely with Parliament on these matters, not least because they merit careful consideration, alongside decisive action by Ministers and senior officials. The Joint Committee on the National Security Strategy, led by my hon. Friend the Member for Warwick and Leamington (Matt Western), plays a vital role in providing that appropriate scrutiny. I say that not just as a Government Minister, but as a former member of his Committee. The same principle applies to the ISC, which does important work. I take this opportunity to thank the Chair and the whole Joint Committee for undertaking this work and publishing a comprehensive report as quickly as they have.

My hon. Friend the Chair highlights some important aspects of the report’s conclusions, recommendations and findings, following the work that the Committee undertook. As I have said, the Government approach this issue, and will consider the Committee’s report, with the utmost seriousness. I can give him the assurance that he seeks that the Government are now carefully considering the findings of the report. I give him and the House an absolute assurance that we will respond within the agreed timeframe. He mentioned a couple of other points that I will respond to briefly now, although I am happy to engage with him in more detail, should he think that necessary.

My hon. Friend mentioned the role of the CPS. He will understand that as a Government Minister, I am incredibly limited in what I can say about the CPS, because it is operationally independent of Government. He makes a fair challenge, and we will look carefully at the report’s findings in this area. He also mentioned the National Security Act 2023. While I am not in any way complacent about that legislation, we are in a much stronger position than we were. We keep these matters under review, and along with colleagues across Government, we are constantly seeking to assure ourselves that the legislative framework is fit for purpose and appropriate. I give him an absolute assurance that we take that incredibly seriously.

Finally, my hon. Friend mentioned the deputy National Security Adviser. Let me take the opportunity again to pay tribute to him for the important work that he does. He is a dedicated public servant, and his contribution to our national security is immense. The Government are grateful for his service, as I am sure is the whole House. I will look carefully at the points that my hon. Friend has made, and we will ensure that they are properly reflected in the response he receives from the Government.
