MI5's Alert on China's Persistent Espionage Efforts in the UK

A surprising contact on the professional network. An offer of employment from a headhunter, most likely a young woman, based in China. The opportunity to earn perhaps £20,000 on the side preparing a handful of geopolitical analyses for a Chinese company peppered with “non-public” or “insider” insights. Compensation in digital currency or physical money favored.

It may seem clear, in this scenario, that something about this approach would be amiss. Nevertheless, Beijing's influential Ministry of State Security continues to view it valuable to deploy recruitment consultants to attempt this – prompting MI5 to issue multiple warnings about their operations online.

Large-Scale Contact Attempts on Professional Networks

In 2023, the head of MI5 Ken McCallum said Chinese agents were contacting Britons on the platform on an unprecedented level, at a rate of 10,000 over the preceding two and a half years, attempting to obtain political, industrial, military and scientific secrets. However a new initiative aimed at politicians and Westminster has led the spy agency to act again.

A spying alert was issued on this week via the administrative teams of the Commons speaker and his House of Lords equivalent: a single slide after the persistent attempts of certain individuals and other operatives to reach out to MPs, peers, their assistants, economists, thinktanks – anybody who might provide information.

Security Strategy and Legislative Changes

In the typical manner of UK security services, there was no publication of the security advice from MI5 or the Home Office. But the service was aware its advisory document would leak once it was sent electronically out to Westminster. Sharing it in the media assists the wider public better identify interactions with a fraudulent intent.

This warning has the effect of uncovering additional details from in and around Westminster, although that is not the agency's primary purpose. The service aims for public figures to understand that simply because exchanges on professional networks are less overtly risky as on other social platforms, it doesn't imply they are completely safe.

Nor is internal security service understood to have been reacting to any specific incident in parliament, although the recent actions occur after the awkward collapse of the legal case of a former parliamentary aide Christopher Cash and his friend Christopher Berry on a legal detail in recent months.

The two had been accused of working for China – a allegation they denied – but inability to complete a prosecution under the now repealed Official Secrets Act led to concerns that the UK's political system had been insufficiently defended.

Revised Laws and Beijing's Long-Term Interests

Legislation has since been updated, and the MI5 slide includes a reminder of its replacement: “Individuals involved in spying operations face significant criminal penalties under the National Security Act.” It is a crime if a person participates in behavior that is or is likely to “significantly help a overseas spy agency”.

An obvious inquiry, however, is what China has to gain. A politician who is outside ministerial roles will have limited knowledge of classified material, and an contact of theirs less so. But the Chinese government is particularly focused in parliament: for a time, in 2020 and 2021, the UK’s approach to China on matters such as Huawei or the human rights situation or genocide was being influenced by MPs.

Cultural Differences and Ongoing Digital Threats

To a degree there are distinct approaches as well. Authoritarian governments like China’s export information gathering methods and the scale of its spy network is enormous, employing three hundred thousand individuals. Chris Inglis, a American cybersecurity head under the US administration, said it was sometimes estimated that “China have more English speakers involved in this than Western agencies have English speakers”.

Beijing is willing to cultivate people over the long term and at times even the agencies have found it difficult to distinguish between legitimate relationships and spying. “Beijing has a low threshold for what information is considered to be of value,” the minister responsible a government official told parliamentarians on this week, but a rapid shift in the government situation may result in an individual quickly peripheral becomes important.

Another way to consider the relentless efforts at secret intelligence collection is in the wider context of the geopolitical contest between China and the west at a level below the point of outright war. The nation has stepped up its hacking efforts, with the Salt Typhoon penetration of phone and data networks in numerous nations, and the Volt Typhoon breach of millions connected equipment.

Chinese authorities is involved in relentless attempts to find covert sources on UK politics via digital means because it seeks to be provocative, to display power and because it has the capability.
