Voting started Sunday in Poland’s presidential election runoff between the conservative incumbent, President Andrzej Duda, and liberal, pro-European Union Warsaw Mayor Rafal Trzaskowski, AP reported.

Duda is backed by the ruling right-wing party and the government, as he seeks a second 5-year term. Trzaskowski, a former European Parliament lawmaker, runs for the main opposition Civic Platform party that was in power in from 2007 to 2015.

In the first round, Duda got 43.5% and Trzaskowski 30.5%, but in the second round he is expected to get support from many voters who backed candidates who have now been eliminated.
