Marcin Zaborowski was quoted by The New York Times:

"This will be a very different style of government," said Marcin Zaborowski, a Polish expert at the European Union Institute for Security Studies in Paris. "Tusk has struck a balance between technocrats and politicians. Tusk will be hands-on when it comes to economic policy. But on other issues, such as foreign and judicial policy, he can expect some tough problems ahead with the president." The New York Times
