Sir Keir Starmer said the UK would join northern European allies in intercepting the tankers, in an attempt to “go after” the sanction-breaking ships “even harder”.
The PM has given approval for the UK to start seizing shadow fleet vessels as he travels to Helsinki, Finland, for a summit with national leaders from the Joint Expeditionary Force (JEF).
The military coalition of 10 northern European countries, comprising of the UK, Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, the Netherlands, Norway and Sweden, aims to defend against Russian incursions.
Moscow’s shadow fleet is reported to be made up of more than a thousand ageing tankers.
They illicitly ship oil and other goods out of Russia by flying the flags of other countries, with the aim of evading sanctions imposed by the West since the invasion of Ukraine began.Finland, Sweden and Estonia have recently intercepted suspected shadow tankers travelling through the Baltic.
Closing off British waters to the shadow fleet is aimed at forcing the Russian vessels into taking longer, more costly sea routes, or risk being intercepted by the UK.
“We are living in an increasingly volatile and dangerous world, facing threats from different fronts across the world every day,” Starmer said.
“As prime minister my first duty is to keep this country safe and protect British interests here and abroad.
“(Russian President Vladimir) Putin is rubbing his hands at the war in the Middle East because he thinks higher oil prices will let him line his pockets.
“That’s why we’re going after his shadow fleet even harder, not just keeping Britain safe but starving Putin’s war machine of the dirty profits that fund his barbaric campaign in Ukraine.
“He and his cronies should be in no doubt, we will always defend our sovereignty and stand with Ukraine for as long as it takes.”
British forces have already been involved in tracking shadow fleet vessels for several years, and have supported operations by other countries to seize the ships.
