MI5 has issued an espionage alert to MPs and peers in the House of Lords warning that Chinese intelligence services were “relentless” in trying to “interfere” and “influence” Parliament.

Commons Speaker Sir Lindsay Hoyle and his counterpart in the House of Lords, Lord McFall, circulated the “espionage alert” to MPs claiming that the Chinese Ministry of State Security was “actively reaching out to individuals in our community”.

The alert said Chinese spies were using “false personas”, posing as headhunters and connecting with individuals in Parliament to “collect information and lay the groundwork for long-term relationships”.
