Evil reigns in Poland and we want to fight it. That's reason enough, you don't need any other justification. Those are the words of Donald Tusk aimed at the ruling Law and Justice Party. Polish ex- Prime Minister and former President of the European Council will give up his role as president of the European People's Party to be able to fully engage in Polish affairs and to run the opposition Civic Platform party. But how much does Tusk still understand the Polish politics? What can he bring into a political arena except a heavy criticism of the Law and Justice? Just attacking Law and Justice might not be enough for Tusk to be successful. That's what Professor of Politics and Contemporary European Studies at the University of Sussex Aleks Szczerbiak thinks. He even said that the Law and Justice and its leader Jaroslaw Kaczynski are perhaps pleased with Tusk being back. Listen to our conversation.
