Warsaw Mayor votes in Polish presidential election

The main opposition candidate in Poland's presidential elections , Warsaw mayor Rafal Trzaskowski, cast his ballot on Sunday as the country went to the polls.

Trzaskowski, 48, is supported by the centrist Civic Platform party.

He's seen as the leading challenger to President Andrzej Duda, a conservative backed by the nationalist ruling Law and Justice party who's seeking a second 5-year term.

Nine other candidates are also taking part in the race for the presidency.

Whether Duda wins or not will determine whether the ruling party keeps its near-monopoly on political power in Poland.

Turnout at noon was over 24% which the State Electoral Commission said was a record for that time in Poland's 30 years of democracy.

Most recent polls showed that no single candidate was likely to reach the 50% required to avoid a runoff given the crowded field of candidates, all of whom are male.

In that case, the two top vote-getters will face each other on July 12.
