Polish Deputy Prime Minister Piotr Glinski, who also serves as the country's minister of culture, lashed out at the country's opposition, accusing it of using the same methods as the Nazis used against Jews in the 20th century.
"The language toward Law and Justice is to exclude, annihilate, dehumanise, delegitimise, as Jews were treated by Goebbels," Glinski said in an interview for the newspaper Wprost on Monday.
The ruling Law and Justice party of Poland has been under fire from both internal opposition and EU officials alike. The opposition has criticised the party's reforms, which give the government more control over the judicial system and the press.
The party has also been criticised by the EU after it ordered a legal examination to determine whether EU legislation is 'compatible' with Polish national laws.
Besides, the group has also been accused of silently supporting right-wing movements after Poland's president Andrzej Duda announced an Independence Day March that took the same route as a nationalist march, banned by the mayor of Warsaw.
European Comission President Donald Tusk, himself a former prime minister of Poland, and a long-time opponent of Duda, has warned the Law and Justice Party that Poland may be excluded from the EU over its policies, and called on the government to 'come to their senses'.
The law was later watered down, removing criminal penalties for violators and settling the diplomatic crisis with Tel Aviv. Warsaw acknowledges that individual Poles did collaborate with the Nazis against their Jewish neighbours, but insists that assigning blame to the whole country is unwarranted.
