MI5's Alert on China's Persistent Espionage Attempts in Britain

An unexpected connection on LinkedIn. A proposal of work from a headhunter, most likely a young woman, based in China. The opportunity to earn perhaps £20,000 part-time writing a small number of political reports for a Chinese company peppered with “non-public” or privileged information. Compensation in digital currency or cash preferred.

It might appear obvious, in this scenario, that an element about this approach would be amiss. However, China’s powerful Ministry of State Security continues to view it worthwhile to use headhunters to attempt this – leading the domestic spy agency to warn repeatedly about their operations online.

Massive Approaches on Social Media

Last year, the head of MI5 Ken McCallum stated operatives from China were contacting UK citizens on the platform on an extraordinary scale, at a rate of ten thousand over the previous two and a half years, seeking political, commercial, defense and technological classified information. But a fresh campaign targeting politicians and parliament has prompted the spy agency to take further action.

A spying alert was distributed on this week via the administrative teams of the Commons speaker and his House of Lords counterpart: a brief presentation after the repeated efforts of certain individuals and other operatives to reach out to Members of Parliament, lords, their assistants, economists, research organizations – anyone who might become a source.

Security Strategy and Legal Updates

In the typical manner of UK security services, there was no official release of the security advice from MI5 or the Home Office. Yet the agency knew its advisory document would leak once it was emailed out to Westminster. Sharing it in the media assists the general population more easily recognize communications with a deceptive purpose.

This warning has the effect of uncovering more information from within parliament, though that is not MI5’s main objective. The service aims for public figures to understand that just because interactions on professional networks are less overtly risky as on X or Facebook, it does not mean they are without risk.

Nor is internal security service understood to have been responding to any specific incident in the legislature, though the burst of activity does come after the awkward collapse of the legal case of a ex-assistant an individual and his friend Christopher Berry on a technicality earlier in the autumn.

Both individuals had been charged of spying for China – a charge they rejected – but inability to successfully conclude a prosecution under the now repealed previous legislation led to concerns that the UK's political system had been insufficiently defended.

Revised Laws and China's Long-Term Goals

Legislation has since been updated, and the MI5 slide contains a reminder of its successor: “Individuals involved in espionage activity face significant legal consequences under the National Security Act.” This constitutes a criminal offense if somebody participates in conduct that could potentially “significantly help a foreign intelligence service”.

An obvious inquiry, however, is what China has to achieve. A politician who is outside ministerial roles will have restricted knowledge of sensitive information, and an associate of theirs less so. Yet the Chinese government is also interested in the legislative body: for a time, in recent years, the Britain's approach to China on issues such as the telecom firm or the Uyghur repression or genocide was being driven by parliamentarians.

Cultural Differences and Persistent Cyber Threats

To a degree there are distinct approaches too. Authoritarian governments like China’s utilize intelligence collection methods and the size of its intelligence apparatus is vast, employing three hundred thousand people. Chris Inglis, a US national cyber director under president Joe Biden, said it was sometimes estimated that “China have more English speakers involved in this than Western agencies have English speakers”.

The Chinese government is prepared to cultivate contacts over the extended period and at times even the agencies have found it difficult to distinguish between legitimate relationships and espionage. “China has a low threshold for what information is considered to be of value,” the minister responsible Dan Jarvis informed MPs on this week, but a sudden turn in the political cycle may mean someone quickly peripheral becomes important.

Another way to consider the continuous efforts at covert intelligence collection is in the broader framework of the geopolitical contest between China and the west at a level below the point of direct conflict. China has stepped up its cyber operations, with the one campaign infiltration of phone and data networks in 80 countries, and the Volt Typhoon breach of millions internet devices.

Chinese authorities is involved in relentless efforts to identify secret informants on British democracy online because it wants to be provocative, to display influence and because it can.
