China Spying Case

Debate between Iain Duncan Smith and Mark Pritchard

Tuesday 28th October 2025 Commons Chamber

[Mark Pritchard]

If we have the directors of all the intelligence agencies suggesting that China is a threat, it does not get much better than that. We have great deputy national security advisers, but their line managers—their directors, their bosses—were also clearly stating that China was a national security threat. In fact, the word “threat” is mentioned 284 times in that 207-page report.

The key word in this whole episode involving the deputy National Security Adviser—that is, the DNSA for intelligence, defence and security, not the other two remaining DNSAs, unless the Minister wants to correct me—is “active”. The question is whether China was an active threat, as underscored by the testimony to the Joint Committee on the National Security Strategy yesterday. The evidence in the ISC’s report would suggest that China has been known to be an active threat for some time. I have mentioned the various reviews. Indeed, in his own witness statement, the DSNA refers to China conducting “large-scale espionage operations”. Again, this is not a historical reference or a past-tense reference; it is clearly referring to the here-and-now operations taking place today. There is clearly an active threat, not just a general or undetermined threat.

China being an active threat was also underscored by the director general of the Security Service’s recent speech, in which he referred to China’s

“cyber-espionage…clandestine technology transfer…interference in UK public life”

and

“harassment and intimidation of opponents”.

Once more, these threats are not just historical; they are current and active, happening in the UK right now. They have not stopped. They are increasing. They continue.

[Sir Iain Duncan Smith]

I am listening carefully to my right hon. Friend’s excellent speech. Did he see, in the testimony yesterday, the intervention in which Sir Chris Wormald suddenly said that he did not believe that Ken McCallum, the chief of MI5, had described China as a threat? He intervened on the DNSA to make that point. That is fundamentally untrue, is it not?

[Mark Pritchard]

My right hon. Friend makes a good point. I think hon. Members will take their own view on who they think is the expert on national security. I think it will be Sir Ken McCallum, who is a long-serving and distinguished member of the UK intelligence community.
