In 2017, a far-right youth organisation called All-Polish Youth issued a series of “political death certificates” announcing the demise of high-profile pro-European politicians. Among them was Paweł Adamowicz, the long-serving mayor of Gdansk, famous in Poland for his robust defence of refugees and promotion of LGBT rights. “Cause of death:” it stated, “Liberalism, multiculturalism, stupidity.”  Adamowicz was stabbed on stage at a charity concert on Sunday evening, and died on Monday afternoon. He leaves behind him a country in mourning – but for his supporters, the sadness is tinged with anger.
