Final vote count gives conservative candidate 50.89 percent, while his liberal rival receives 49.11 percent, as reported Aljazeera.
Poland’s electoral commission has declared nationalist Karol Nawrocki the winner of the country’s presidential election.
With all votes counted, the commission said on Monday that Nawrocki, a staunch conservative backed by the opposition, had won 50.89 percent of votes in a tight run-off race against liberal Warsaw Mayor Rafał Trzaskowski, who took 49.11 percent.
The election participation rate was 71.63 percent.
Nawrocki, 42, a historian and amateur boxer who ran a national remembrance institute, will represent the country in the presidency for five years.
An early exit poll released on Sunday evening had suggested Trzaskowski was headed to victory before updated polling began to reverse the picture a couple of hours later.
Nawrocki will succeed Andrzej Duda, also aligned with the nationalist conservative Law & Justice (PiS) whose second and final term ends on August 6.
According to the report Nawrocki’s victory was helped by strong support from the MAGA movement in the US.
