In pictures: Polish summit reaction
Pawel Grzeskowiak, 34, Warsaw

Mr Grzeskowiak, 34, a lawyer, says: "I think in the end it was a success because the president and the prime minister didn't block the whole summit and we got some concessions.

"We didn't get 100% of what we wanted, but at least we maintained the Nice voting system for the next ten years. We'll see what happens in 2017."
