A recent flare of arrests

We’re seeing an increasing number of who we would describe as ‘proxies’ being recruited by foreign intelligence services and these arrests are directly related to our ongoing to efforts to disrupt this type of activity.

M15 security director Ken McCallum claimed last week that Russia is committed to “creating havoc and destruction.”
He also stated that “In the last year, we and the police have disrupted a steady stream of surveillance plots with hostile intent aimed at individuals Russian leaders perceive as their enemies,”
On their part, the Kremlin have denied any accusations that it has been connected to British sabotage, claiming that the UK blames Russia whenever something “bad” happens in the Kingdom.
Anyone who might be contacted by and tempted into carrying out criminal activity on behalf of a foreign state here in the UK should think again.
National Security Act, 2023

The National Security Act of 2023 was created to help protect the UK against foreign espionage by increasing the government’s power of investigation and litigation.
The section used in this case was Section 3, “assisting a foreign intelligence service”.
UK corporations and executives have criticized the act, which carries multiple sections targeting those groups’ use of information.
