Poland's incumbent President ANDRZEJ DUDA has been re-elected after defeating RAFAL TRZASKOWSKI in the presidential vote.

The Poland's National Electoral Commission said DUDA won 51.2% of the votes, which is the country's slimmest presidential election victory since 1989.

President DUDA is a social conservative allied with the government led by the nationalist Law and Justice Party, while TRZASKOWSKI is the socially liberal mayor of Warsaw.
