Vladimir Kara-Murza, an opposition activist and former journalist from Russia with British citizenship, has been sentenced to a 25-year prison term. He was found guilty of charges related to his criticism of the Ukrainian conflict, including spreading “false” information about the Russian army, being involved with an “undesirable organisation,” and treason. This verdict is the latest in a string of measures against critics of the Kremlin, who have either been detained or forced to flee Russia. Despite denying all charges, Kara-Murza was given the maximum sentence sought by the prosecutors, the longest ever imposed on an opposition figure since the Ukraine crisis began. He has vowed to stand by his words and proclaimed his innocence, and stated that he is proud of his actions. The judge presiding over the case sentenced Kara-Murza to serve his sentence in a “strict regime correctional colony,” and imposed a fine of 400,000 roubles ($4,900; £4,000) on him. This tough sentence highlights the authorities’ readiness to silence and neutralize any perceived threats to the political system in Russia, and marks a significant setback for free speech and human rights in the country. The proceedings were closed to most journalists and foreign ambassadors, and only a handful of Russian state media personnel, the defendant’s mother, and his lawyer were granted access.
