The designated Czech Prime Minister Andrej Babiš said that the European Union should not push Czechs over their refusal to shelter asylum-seekers, because it could strengthen extremist parties in the country. The European Union’s executive will sue Poland, Hungary and the Czech Republic in the bloc’s top court for their refusal to host asylum-seekers, Brussels said on Thursday. Babiš, whose government is due to be appointed by President Miloš Zeman on Dec. 13, repeated his country’s stance on migrants.
