Polish President Karol Nawrocki announced on Friday his decision to strip Ukrainian President Volodymyr Zelenskyy of the Order of the White Eagle, Poland's highest state honor.
The decision follows outrage in Poland after President Zelenskyy renamed a Ukrainian army unit after a nationalist insurgent paramilitary group. This militia was responsible for massacres against Poles during World War II.
The move by the hard-right president is likely to spark a severe diplomatic crisis between the two nations. Polish Prime Minister Donald Tusk has appealed to both Poland and Ukraine not to waste the solidarity between allies amid the Russian invasion of Ukraine.
