New action to disrupt and deter threats to UK, as MI5 issues espionage alert

• MI5 issues alert over Chinese spying in Westminster.

• Security Minister calls out ‘covert and calculated attempt by China to interfere with our sovereign affairs' and vows to take measures to protect security. 

• New action plan to disrupt and deter spying will include legislation to update national security powers.

The government has set out new action against espionage threats to the UK, as MI5 issues an alert to MPs, Peers and Parliamentary staff after finding that Chinese intelligence officers are attempting to recruit people with access to sensitive information about the British state. 

The UK's domestic intelligence service named two online profiles that are believed to be legitimate headhunters working for Chinese intelligence officials to build relationships with targets on sites like LinkedIn. Espionage alerts are one of the main tools used to undermine spies' ability to operate.

Security Minister Dan Jarvis has told MPs that he will coordinate a new Counter Political Interference and Espionage Action Plan to disrupt and deter spying from states like China. 

The plan will see the intelligence services deliver security briefings for political parties and issue new guidance to election candidates to help them recognise, resist and report suspicious activity; work with professional networking sites to make them a more hostile operating environment for spies; and tighten rules on political donations through a new Elections Bill.  

He will add that the government will continue to take further action against China-based actors involved in malicious cyber activity against the UK and our allies. 

Security Minister, Dan Jarvis MBE, said: 

“Today we've taken action to expose a covert and calculated attempt by China to interfere with our sovereign affairs. This government's first duty is to keep the country safe, which is why I've announced new action to give security officials the powers and tools they need to help disrupt and deter foreign espionage activity wherever they find it. 

“As a country with a long and proud history of trading around the world, it's in our interests to continue to seek an economic relationship with China, but this government will always challenge countries whenever they undermine our democratic way of life.”

Praising the work of the security services, the Security Minister also announced new investment in the tools and capabilities used by officials who work to keep the UK safe.

£170 million will be invested in renewing the sovereign and encrypted technology that civil servants use to safeguard sensitive work. A further £130 million will be invested on projects such as building Counter Terrorism Policing's ability to enforce the National Security Act, and fund the National Cyber Security Centre's and National Protective Security Authority's work with critical businesses to protect their intellectual property.

He also informed Parliament that the government had completed the removal of surveillance equipment manufactured by companies subject to the National Intelligence Law of the People's Republic of China from all sensitive sites the government operates around the world. 

All this work aligns with the government's plan to cooperate with China when it is in the UK's national interest to do so, and challenge China when it threatens the UK's national security. 

Earlier this month, the government introduced the new Cyber Security and Resilience Bill to help protect organisations from cyber threats, including those posed by states like China. It follows existing commitments to increase defence spending to the highest level since the end of the Cold War. 

The National Security Act also gives the government the power to prosecute those engaging in espionage activity. Offences include obtaining protected information, assisting a foreign intelligence service, and obtaining a ‘material benefit' from a foreign intelligence service.

The National Protective Security Authority, the protective security arm of MI5, issued new guidance to Parliamentarians and Parliamentary staff on the threat posed by espionage and what individuals can do to deter the threat and protect themselves in October 2025 (here).
