Vladimir Putin’s cousin and the second richest man in Russia are the latest Kremlin supporters to be sanctioned by the UK government.
Also a relative of Putin, Anna Tsivileva is the chairman of the famous Russian coal mining company, Kolmar Group Corporation, which is also under sanctions.
Her husband, Sergey Tsivilev, is governor of the coal-rich Kemerovo region and the couple are said to have “benefited significantly” from their relationship with the Russian leader.
Financier Vladimir Potanin is the regime’s most important supporter in Moscow, buying up Rosbank and a stake in Tinkoff Bank in the period since Russia’s invasion of Ukraine.
The Foreign Office said the government was also working with international allies to introduce new measures to prevent Russia from accessing UK trust services.
“As long as Putin continues to attack Ukraine, we will use sanctions to weaken Russia’s war machine,” the spokesman said.
“Today’s sanctions show that nothing and no one can get off the table, including those within Putin’s inner circle.”
It comes as official figures show that Britain sharply reduced oil imports from Russia shortly after the invasion of Ukraine.
However, data from the Office for National Statistics also shows that Britain still imported about 140 million pounds of Russian refined oil in April, two months after the war in Ukraine began.
This represents a drop of around £410 million in refined oil imports from Russia in February, the ONS said. This is when Russia is the UK’s largest supplier.
Now, Russia is the UK’s sixth largest supplier with the UK ramping up supplies from other countries including the United Arab Emirates, Saudi Arabia and Belgium.
Refined oil includes gasoline, diesel and heating oil, all of which saw prices skyrocket after the conflict.
