Official Secrets Act Case: Witness Statements

Debate between Lindsay Hoyle and Chris Ward

Thursday 16th October 2025 Commons Chamber

[Chris Ward]

Having now had the opportunity to read these statements, Members will have been able to confirm for themselves what the Prime Minister and other members of the Government—

[Mr Speaker]

Order. May I just say—[Interruption.] No, you are going to hear it, whether you like it or not. Mr Tugendhat, I expect better from you. You will be wanting to catch my eye, and this is not the best way to do it. Can we please show a little bit more respect, which I normally get from you?

[Chris Ward]

Thank you, Mr Speaker.

Having now had the opportunity to read the statements, Members will be able to confirm for themselves what the Prime Minister and other members of the Government have stated repeatedly: the DNSA faithfully, and with full integrity, set out the position of the previous UK Government and the various threats posed by the Chinese state to the UK, and did so in order to try to support a successful prosecution.

The first and most substantive witness statement is from December 2023, under the last Government. The second and third, which are both much shorter, are from February and August 2025 respectively. It is clear from these statements that the substantive case and evidence submitted by the DNSA does not change materially throughout, and that all three documents clearly articulate the very serious threats posed by China. The second witness statement, in particular, highlights the specific details of some of the cyber-threats that we face, and emphasises that China is the “biggest state-based threat” to the UK’s national security. The third statement goes on to state that the Chinese intelligence services are

“highly capable and conduct large scale espionage operations against the UK to advance the Chinese state’s interests and harm the…security of the UK.”

It is clear from this evidence, which all can now see, that the DNSA took significant strides to articulate the threat from China in support of the prosecution. The decision on whether to proceed, as the Prime Minister made clear yesterday, was taken purely by the CPS. It is also clear that the three statements are constrained by the position of the Conservative Government on China at the time of the alleged offences.

As the Prime Minister said yesterday and the Security Minister said on Monday, this Government’s first priority will always be national security and keeping this country safe. We wanted this case to proceed. I am sure all Members of the House did, and I know you did too, Mr Speaker. We are all profoundly disappointed that it did not.

[Chris Ward]

I thank the shadow Minister for that and, as I say, I do recognise how personally important this matter is to him and to many Members of the House.

On transparency, the Security Minister has given two statements to this House. The Prime Minister gave what I think we can all agree was a rather lengthy statement yesterday, and he used the pretty unusual process of publishing the evidence in full yesterday, so transparency is something the Government are trying to provide.

The key point the shadow Minister made was about why the Prime Minister or Ministers did not interfere or try to do so. As the Prime Minister made clear yesterday, this was a matter for the CPS independently, and an important principle of this Government—[Interruption.] Evidence was provided independently by the deputy National Security Adviser. The Prime Minister made it clear, and this is the bit I find confusing—[Interruption.]

[Mr Speaker]

Order. Mr Cartlidge, you are very energetic there and even I can hear you from here, so please can we have a little bit less?

[Chris Ward]

This is the bit that I find slightly confusing about the Opposition’s approach. On Monday and today as well, they have accused this Government of political interference, including by the National Security Adviser. The Prime Minister has made it absolutely clear that that is completely untrue. On the other hand, they are saying there should have been political interference, and that the Prime Minister should have directed or tried to help the CPS. The Prime Minister has made it very clear that that is not the case, and that no Prime Minister and no Government would interfere with the CPS on a decision to charge, which is entirely for it to make.

In terms of the evidence in the three statements put forward yesterday, there is clear consistency across them. They all set out the very, very serious threats that China poses. I do not think anyone can think that that is not the case. [Interruption.] It was provided independently by the deputy National Security Adviser without interference from anyone else. They are his words. It is his choice what happens, and that is what happened.

We have been through this several times—on Monday, yesterday and today. The Prime Minister has provided the evidence. It is there for Ministers and Members to see. Ultimately, the decision was taken by the CPS not to proceed and we are all disappointed in that.

[Mr Speaker]

I call the Chair of the Foreign Affairs Committee.

[Emily Thornberry (Islington South and Finsbury) (Lab)]

It seems to me that the issue is this: given that all the deputy NSA’s witness statements refer to China as a threat, I cannot understand why the CPS took the nuclear option of collapsing the case rather than leaving it to a jury. Twenty years as a criminal barrister has given me absolute faith that the jury would have spent no time on how many angels can dance on the top of a pin, but would simply have looked at whether or not China was an enemy. They would have found it very easy to decide that that is exactly what it was and then moved on to whether or not these men had been spying on behalf of China. It does seem to me that the decision should have been left to a jury. Does my hon. Friend have any idea why on earth the CPS dropped the case?

[Chris Ward]

As I say, this was a decision taken by the CPS independently, with no interference or involvement from the Government. Members may or may not sympathise with that decision. It was a CPS decision. That is why it is important that the evidence is in the public domain now and that everyone can judge from that how things proceeded.

I will just make one final point. Obviously, the CPS decision was not based purely on the evidence put forward by the DNSA. It was based on much wider evidence collected over a much longer period, so the decision on whether to proceed was taken by the CPS on a much broader evidential basis.

[Mr Speaker]

I call the Liberal Democrat spokesperson.

[Jess Brown-Fuller (Chichester) (LD)]

Yesterday, we saw finger pointing and “gotcha” moments from both the Government and the Opposition Benches during Prime Minister’s questions, but the release of the witness statements last night provides further questions for both sides, including what pressure was being applied to the right hon. Member for Tonbridge (Tom Tugendhat) and the hon. Member for Rutland and Stamford (Alicia Kearns) from within their own party to dampen down their criticisms of China. This whole thing makes an absolutely mockery of what is a serious collapse of a case and a threat to our national security—a threat that is not going away but will only increase.

Did the CPS tell the Government in advance that the case was at risk of collapsing? Did it ask the Government to be more explicit in their wording, and if so, why were the Government not more explicit? Will the Minister commit today to a statutory independent inquiry, which would provide radical transparency and ensure that the right lessons are learned so that this does not happen again?

[Chris Ward]

I can promise that I will try to avoid all “gotcha” moments and finger pointing. On the question of when the CPS informed the Government, my understanding, and the Prime Minister made this clear yesterday, is that the Prime Minister was informed very shortly before the case collapsed—a matter of days before. That is on the record—it was in the House, if you need to refer to that, from the Prime Minister.

In terms of future inquiries, I should have said to my right hon. Friend the Member for Islington South and Finsbury (Emily Thornberry) that this is an issue Select Committees will want to look at as well. There is a normal process for that, but I am unable to go beyond that today.

[Mr Speaker]

I call the Chair of the Joint Committee on the National Security Strategy.

--- Later in debate ---

[Chris Ward]

As I say, parliamentary scrutiny and transparency is something that, despite the allegation, we are trying to provide with statements and by publishing evidence. I am sure, going forward, that that is something that will carry on. I will come back to my hon. Friend on the precise mechanism for how we will do that, but I am sure people will be made available to his Committee.

[Mr Speaker]

I call the Father of the House.
