The leader of Poland's Law and Justice party Jaroslaw Kaczynski accused Donald Tusk, the head of the European Council in violation of the basic principles of the EU.

According to him, Donald Tusk shouldn’t have violated the principle of neutrality in the internal affairs of the EU Member States. "Donald Tusk openly supports the Polish opposition, which does not hide its intention to overthrow the state by anti-constitutional methods," Kaczynski.

Kaczynski added, that all those who violate the principle of neutrality "in no case can count on our support."
