Britain is facing what security experts describe as an increasingly aggressive Russian hybrid warfare campaign linked to London's military and political support for Ukraine.

According to the report, recent incidents include alleged cyberattacks, sabotage, arson, disinformation campaigns and maritime confrontations that British officials and analysts believe are designed to weaken the United Kingdom without triggering direct military conflict.

Among the incidents cited are fires targeting properties associated with Prime Minister Keir Starmer, warning shots fired by a Russian warship near a civilian yacht shortly after British authorities seized a suspected sanctions-evasion vessel, and cyberattacks that disrupted Jaguar Land Rover's production and affected Britain's National Health Service.

The article argues that Moscow increasingly views Britain as one of its principal adversaries, particularly as the United States under President Donald Trump has sought to reduce its involvement in the Ukraine conflict.

Former British defence attaché John Foreman says relations between London and Moscow have deteriorated sharply, while researcher Helena Ivanov argues Russia is also using misinformation to influence public opinion and encourage opposition to sanctions and military aid for Ukraine.The report also references concerns about previous Russian influence efforts surrounding Brexit and British domestic politics.

Prime Minister Keir Starmer has responded by announcing a significant increase in defence spending focused on fighter aircraft, submarines, drones and autonomous weapons, citing NATO assessments that Russia could pose a broader military threat later this decade.

However, some experts caution that hybrid warfare is generally intended to avoid direct armed conflict while maintaining constant pressure on rival states.
