Poland’s President Andrzej Duda came top in the first round of the presidential election, the majority of results showed on Monday. He fell short of the overall majority needed to avoid what looks set to be a tight run-off vote on July 12, Reuters reports.

Duda, an ally of the ruling nationalist Law and Justice (PiS) party, got 45.73 percent of the vote, according to results based on 82.2 percent of the total number of polling districts.

Liberal Warsaw Mayor Rafal Trzaskowski, who is standing for the largest opposition party, the centrist Civic Platform (PO), came second with 28.51, officials say.
