The UK has imposed sanctions on a Russian military officer accused of helping poison former double agent Sergei Skripal with novichok in Salisbury. Denis Sergeev, who was charged by the Met Police over the attempted murder, has been sanctioned under the chemical weapons sanctions regime. The Foreign Office has also imposed sanctions on people and entities linked to Russia, including the Wagner mercenary group and companies based in China, Turkey, and central Asia supplying parts to Russia. The sanctions aim to push back on Russia's foreign policy and disrupt the supply of vital equipment for Putin's war machine.
