Poland votes in 'most important' election since communism

Poles began voting on Sunday in parliamentary elections as the ruling populists bid for a third consecutive term in power.
Opinion polls indicate the nationalist Law and Justice (PiS) party will get the most votes but may struggle to build a governing coalition, giving a chance to the opposition led by former EU chief Donald Tusk. Some 29 million people are eligible to vote, including half a million registered abroad.
