Poland's Duda holds slim lead in presidential election, exit poll suggests
Poland's incumbent President Andrzej Duda holds a slim lead after Sunday's presidential election, according to an exit poll.
The poll on Sunday showed Mr Duda, an ally of the conservative government, with 50.4% of the vote.
He was pitted against the socially liberal Warsaw mayor Rafal Trzaskowski.
The vote has been widely seen as a battle for the country's future as well as its strained relations with the European Union.
Mr Trzaskowski received 49.6% of the vote, according to the exit poll, which pollster Ipsos said had a margin of error of two percentage points.
A second poll - combining exit poll data with partial official results - suggested Mr Duda received 50.8% of the vote. Official results are expected on Monday.
"I want to thank everyone that voted for me," Mr Duda said shortly after the exit poll was announced.
Mr Trzaskowski told his supporters: "The result has probably never been so close in Polish history, we've never felt the power in our vote so much."
Mr Duda said turnout was nearly 70%, which, if confirmed by election officials, would be a record high for a presidential election in the country.
A win for Mr Duda is expected to herald controversial changes to the judiciary and continued opposition to abortion and gay rights.
He came under fire during the election, including for a speech in which he said LGBT rights were an "ideology" more destructive than communism.
