Russia’s Supreme Court on Monday barred the liberal Yabloko party from contesting September’s parliamentary elections, sidelining the only officially registered party that opposes Moscow’s war in Ukraine. More than four years after Russia launched its full-scale war, the decision highlights the authorities’ intolerance of anti-war views and further narrows the already limited space for dissent in Russian politics. “Excluding Yabloko from the election means refusing dialogue with people who ask questions that are uncomfortable for the authorities,” Nikolai Rybakov, the party’s leader, said, vowing to appeal the decision.
