With all votes counted, right-wing historian Karol Nawrocki has been elected Poland`s new president, the state electoral commission (PKW) said, writes BBC.

PKW said Nawrocki won 50.9% percent of the votes – ahead of Warsaw`s liberal mayor Rafal Trzaskowski on 49.1% percent.

It`s a sensational turnaround from the result of the first exit poll – published immediately after voting ended at 21:00 local time (19:00 GMT) on Sunday – that showed Trzaskowski winning on 50.3% to Nawrocki"s 49.7%.

Trzaskowski had claimed victory after the first exit poll, while Nawrocki cautioned that the results were too close to call.

"We won, although the phrase "razor`s edge" will forever enter the Polish language and politics", Trzaskowski told his supporters.

His wife, Malgorzata, jokingly told the crowd, "I`m close to having a heart attack".

Nawrocki, had said after the result of the first exit poll, "Let`s not lose hope for this night. We will win during the night, the difference is minimal. I believe that we will wake up tomorrow with President Karol Nawrocki".
