Poland presidential debate puts Ukraine and Europe centre stage

Rafa Trzaskowski, from the governing pro-EU coalition, faces Eurosceptic populist rightwing historian Karol Nawrocki ahead of run-off

Polish presidential candidates offered different visions of Poland and its relations with Ukraine in a televised debate ahead of next week's run-off, which remains on a knife-edge.

During a head-to-head debate lasting two hours, the centrist Warsaw mayor Rafa Trzaskowski, from prime minister Donald Tusk's governing pro-European coalition, faced the Eurosceptic historian Karol Nawrocki, backed by the populist rightwing Law and Justice party (PiS).
