WARSAW - Poland will hold a presidential election on June 20 following the death of Lech Kaczynski and opinion polls show acting president Bronislaw Komorowski will win it comfortably.

Komorowski automatically took the helm on Kaczynski's death in his capacity as speaker of parliament, number two in the state hierarchy. He is also the presidential candidate of Prime Minister Donald Tusk's ruling Civic Platform.

"Komorowski signed all the documents, hence setting the date of the election for June 20," Komorowski's spokesperson, Jerzy Smolinski said.

Kaczynski, his wife Maria and 94 others, mostly senior, military and political officials, were killed in a plane crash in Russia on April 10.

A slew of opinion polls this week have shown the gently spoken Komorowski, 57, will trounce his rivals for the presidency, a mainly ceremonial post which includes key veto powers over legislation and a say in foreign policy.

Kaczynski's twin brother Jaroslaw, 60, a former prime minister who heads the main opposition Law and Justice party is expected to decide by Saturday whether to run. - Reuters
