The United Kingdom has signalled a tougher stance against Russia’s “shadow fleet,” with Defence Secretary John Healey confirming that British forces are now prepared to board and detain sanctioned vessels operating in UK waters.
The move follows months of preparation after ministers identified a legal framework earlier this year.
Meanwhile, final approval was recently granted by Prime Minister Keir Starmer, allowing military action against ships suspected of evading sanctions imposed over Russia’s war in Ukraine.
Healey said the delay was necessary to ensure proper training, coordination with allies, and a clear legal basis. He described the development as a strong signal that the UK is ready to act against vessels used to bypass sanctions and fund Moscow’s war efforts.

Also, Russia has been accused of using ageing tankers, often operating without clear national registration, to transport oil covertly. Analysts estimate that a significant portion of its crude exports moves through this shadow network, with several sanctioned vessels reportedly passing through the English Channel in recent months.
Ukrainian President Volodymyr Zelensky welcomed the decision, describing it as timely and critical in maintaining pressure on Russia. He stressed that cutting off illicit oil revenues would weaken Moscow’s war capabilities and improve regional security.
British naval units, including the Royal Navy, have already been working with European partners to monitor suspicious vessels. While no ships have yet been boarded, officials say specialist units have completed training and are ready for potential operations.
The UK government believes targeting the shadow fleet will disrupt a key revenue stream for President Vladimir Putin.
However, authorities have sanctioned hundreds of vessels linked to the network and are using advanced tracking systems to identify targets.
Officials say the first interception could happen soon as part of broader efforts to tighten enforcement of sanctions and support Ukraine.
