The Kremlin has described Poland’s decision to rename the Russian city of Kaliningrad in its official documents as a “hostile act”, as ties continue to fray over the Ukraine war.
Kaliningrad, which sits in an exclave sandwiched between Lithuania and Poland on the Baltic coast, was known by the German name of Königsberg until after the second world war, when it was annexed by the Soviet Union and renamed to honour politician Mikhail Kalinin.
