Voters in Poland are going to the polls Sunday to cast ballots in a tight, runoff presidential election between incumbent Bronislaw Komorowski and challenger Andrzej Duda.
Mr. Duda won the first-round vote earlier this month. Analysts described Mr. Duda's win as one of the biggest shocks in Polish politics in recent years, given that pre-election surveys signaled a relatively easy win for the centrist incumbent.
Mr. Komorowski, a historian and former defense minister, was first elected in 2010 and campaigned for a second term largely on national security challenges.
Conservative Mr. Duda campaigned on promises to lower Poland's retirement age. He also advocated tax cuts and warned of rising prices, if Poland adopts the euro currency.
In Poland, the prime minister leads the government, but the president - elected for a five-year term - heads the armed forces, and has a say in foreign policy and the passage of legislation.
