Hungary has expelled ten Russian diplomats as relations between Budapest and Moscow deteriorate, a notable shift for a country long viewed as Russia's closest ally within the European Union. The move follows a change in government that has moved away from the previous pro-Kremlin stance. Russia has responded by vowing a 'harsh and painful' retaliation against Hungary, signaling a further deterioration in bilateral ties and marking one of the more serious diplomatic ruptures between Moscow and a former close EU partner.
