Poland's parliamentary Speaker has set June 20 as the date for an early presidential election after the death of President Lech Kaczynski in a plane crash 11 days ago.

Bronislaw Komorowski, who is the acting president and will be a candidate, set that date for the first round of voting.

If no candidate wins at least 50 per cent, a second round will be held two weeks later, on July 4.

Elections were originally to have been held this autumn but had to be moved up due to Kaczynski's death April 10 in a plane crash in western Russia.

The crash also killed his wife and 94 others, including many of the country's civilian and military leaders.
