WARSAW (Reuters) - Poland’s ruling eurosceptic Law and Justice (PiS) party has secured the highest number of provincial assembly seats in a regional election on Sunday, an exit poll showed.

The poll by Ipsos pollster showed the conservative PiS winning 32.3 percent in the vote for provincial assembly members, against 24.7 percent for a coalition of centrist parties.

A centrist candidate for mayor of capital Warsaw, Rafal Trzaskowski, was set to win the race against PiS’ Patryk Jaki.
