President Andrzej Duda was marginally ahead in Poland’s presidential election, an exit poll showed on Sunday, in a result with profound implications for relations with the rest of the European Union.

Axar.az reports citing foreign media.

Duda, an ally of the ruling nationalists Law and Justice (PiS), got 50.4% of the vote, according to the exit poll.

Warsaw Mayor Rafal Trzaskowski, the favoured candidate of the main opposition party, the centrist Civic Platform (PO), got 49.6%.

The exit poll by Ipsos has a margin of error of two percentage points for each candidate. Preliminary results are expected on Monday.
