An unexpected contact on the professional network. An offer of employment from a recruiter, probably a young woman, based in China. The chance to earn around £20,000 part-time writing a small number of geopolitical reports for a firm from China containing “non-public” or privileged information. Payment in cryptocurrency or cash preferred.

It might appear obvious, in this scenario, that an element about this approach would be amiss. Nevertheless, Beijing's influential Ministry of State Security continues to view it worthwhile to use headhunters to try it – leading MI5 to issue multiple warnings about their activity online.

Large-Scale Approaches on Professional Networks

In 2023, MI5 chief Ken McCallum stated Chinese agents were approaching Britons on the platform on an unprecedented level, at a rate of 10,000 over the previous 30-month period, seeking political, industrial, military and scientific secrets. But a new initiative aimed at elected officials and Westminster has led the intelligence service to take further action.

An espionage warning was issued on this week via the offices of Lindsay Hoyle and his House of Lords equivalent: a single slide after the persistent attempts of Shirly Shen and Amanda Qiu to reach out to MPs, peers, their assistants, economic experts, research organizations – anyone who might become a source.

Intelligence Approach and Legal Changes

In the typical style of UK security services, there was no publication of the protective guidance from MI5 or the interior ministry. Yet the service knew its briefing note would become public once it was emailed out to Westminster. Republishing it in the media helps the wider public better identify interactions with a deceptive intent.

This warning has the impact of flushing out additional details from in and around parliament, although that is not MI5’s primary purpose. The service wants public figures to understand that just because interactions on LinkedIn are not as toxic as on other social platforms, 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, although the recent actions does come after the embarrassing collapse of the legal case of a ex-assistant an individual and his associate another person on a technicality earlier in the autumn.

The two had been charged of spying for China – a charge they rejected – but failure to successfully conclude a prosecution under the now repealed Official Secrets Act resulted in concerns that the UK's political system had been left unprotected.

Updated Legislation and China's Strategic Interests

The law has since been updated, and the MI5 slide contains a reminder of its replacement: “Those engaging in espionage activity risk substantial legal consequences under the National Security Act.” It is a crime if somebody participates in behavior that is or is likely to “materially assist a overseas spy agency”.

An obvious question, however, is what China has to gain. A politician who is outside ministerial roles will have limited knowledge of sensitive information, and an contact of theirs less so. But the Chinese government is also interested in the legislative body: for a time, in 2020 and 2021, the UK’s China policy on matters such as Huawei or the human rights situation or alleged atrocities was being influenced by MPs.

Cultural Differences and Persistent Cyber Risks

In part there are cultural differences too. Autocratic regimes like Beijing's export intelligence collection methods and the scale of its intelligence apparatus is enormous, engaging three hundred thousand people. Chris Inglis, a US national cyber director under the US administration, commented it was sometimes estimated that “China have greater linguistic capacity involved in this than we [western intelligence] have personnel with language skills”.

Beijing is prepared to develop people over the long term and sometimes even the intelligence services have struggled to differentiate legitimate relationships and espionage. “Beijing has a minimal requirement for what information is deemed to be useful,” the minister responsible a government official informed parliamentarians on this week, but a sudden turn in the political cycle may mean an individual rapidly peripheral turning significant.

Another way to think about the relentless activities at secret information gathering is in the wider context of the international competition between Beijing and the west at a threshold below the point of outright war. The nation has increased its hacking efforts, with the one campaign penetration of phone and data networks in 80 countries, and the another operation compromise of millions connected equipment.

Chinese authorities is engaged in relentless efforts to find secret informants on British democracy online because it seeks to be challenging, to display power and because it has the capability.
