Poland's president has set Oct. 9 as the date for parliamentary elections, opening a campaign certain to be shaped by bitter disputes over the plane crash last year that killed President Lech Kaczynski and other political figures.
The country's second most popular party is Law and Justice, the conservative nationalist force led by the late president's twin brother, Jaroslaw Kaczynski.
That party blames the government of Prime Minister Donald Tusk for the disaster, claiming that ill will toward the late president led to careless security procedures that were among the causes of the crash.
Opinion polls, however, show Tusk's centrist Civic Platform party stands a good chance of keeping power.
President Bronislaw Komorowski announced the date Thursday.
