Security Update: Official Secrets Act Case

Contribution

I took every opportunity to give the right hon. Lady as long as I possibly could so that she could look at the points that we were seeking to raise today. But she has asked me questions that I answered in my earlier responses. I say that to her because it is important that we seek to discuss these things in a reasonable way. Matters relating—[Interruption.] The hon. Member for Harborough, Oadby and Wigston (Neil O'Brien) guffaws from a sedentary position, but I think it is important that we should seek to discuss matters relating to national security in a reasonable and consensual way. That is the approach of this Government. I am genuinely really sorry that the right hon. Lady has taken the opportunity to make a whole series of baseless smears this afternoon. Perhaps we should not be too surprised: the statement that we have heard from the Leader of the Opposition is sadly typical of what we have heard from some of her colleagues in recent days. For days, the Conservative party has been making baseless claims that the Government deliberately collapsed an independent legal process through political interference. There is not a shred of evidence to back up any of the accusations that she has made. I do not think that is a responsible way to discuss matters of national security. I remind the Leader of the Opposition that, whatever Members might say this afternoon, we are here today because of legislation and policy that existed under the previous Government. The Leader of the Opposition referenced the letter that she had written to the Prime Minister. We want to respond to her in a timely fashion, so I will now respond to the points that she made to the Prime Minister. In case she has forgotten, it was she herself who said in September last year: “I have shied away from calling China a threat”. She articulated the previous Government’s policy as Business Secretary, saying in September 2023: “We certainly should not be describing China as a foe”. Those are the right hon. Lady’s own words. Opposition Front Benchers have raised a number of questions, including in the letter published by the right hon. Lady earlier today. I am very happy to set out the Government’s response to her questions. First, on the question of what Ministers knew about the Government’s interactions with the CPS, Ministers were aware that evidence was being provided by the deputy National Security Adviser to the CPS as it built a case for prosecution, as was first agreed under the previous Government. Ministers and special advisers did not take decisions about that evidence and they were not cited in the contents. The deputy National Security Adviser was given full freedom to provide evidence without interference, as was the case before the general election. Secondly, the right hon. Lady asked in her letter whether the Prime Minister was briefed by Ministers or the National Security Adviser about the case. The Prime Minister has already confirmed that he was briefed on the case by officials, not least because the case began under the previous Conservative Government. Thirdly, there have been various reports alleging that in a meeting in September, the National Security Adviser ruled that China could not be defined as a threat and took decisions relating to witnesses or evidence. That is simply untrue. Of course, the NSA takes part in discussions about national security and diplomatic relations—that is literally his job. But any discussions were on the basis that the case would be going ahead and about how to handle the implications. The National Security Adviser was not involved in any decisions about the substance of the evidence. That means, to answer the fourth question raised by the Leader of the Opposition, that he made no decisions about the content of any evidence—[Interruption.] Hon. Members have asked for a thorough explanation and I am giving it to them; they might pay the House the courtesy of listening to the responses. The National Security Adviser made no decisions about the content of any evidence relating to the case itself. This was a matter for the deputy National Security Adviser—a hugely experienced, highly capable senior official who provided evidence under the previous Administration. On questions about when I and other Ministers were aware that the case would not be proceeding, I should say that Ministers were informed after the DPP had made his decision and shortly before reporting restrictions were lifted. Hon. Members will note that I came to the House straight away to make a statement. Finally, on whether it might still have been possible to argue successfully in court that China was a threat regardless of the previous Government’s position not to do so, that was a judgment for the Crown Prosecution Service. However, the deputy National Security Adviser provided evidence reflecting the threats posed by China as the CPS built its case. On the comments, referenced by the right hon. Lady, made by two former Cabinet Secretaries, I note that they have both remarked that the Official Secrets Act was not fit for purpose. Of course, if the Conservatives had been swift in replacing it, we would not be here today. Safeguarding our national security is the most fundamental responsibility of this Government. In 14 years of rule, the Conservative party was slow both to update our national security laws and to adapt to the national security realities that we face today. If we followed the Conservatives’ approach—to ignore and refuse to engage with China—that would undermine our national security. On this side of the House, we will always defend our national interest.
