Warsaw’s liberal mayor and his insurgent populist challenger are locked in a dead heat as they fight for the presidency of Poland, exit polls projected after Sunday’s head-to-head vote, leaving the country tilting between two wildly different political futures.

Local media have extrapolated the data to show that Nawrocki won 50.9% of the votes ahead of Warsaw's liberal mayor Rafal Trzaskowski on 49.1%. PKW is expected to announce the official result later on Monday morning.
