Polish Prime Minister Donald Tusk¹ has claimed victory in parliamentary elections after exit polls gave a clear lead to his Civic² Platform party.

波兰议会选举后民意调查显示，总理唐纳德·图斯克领导的公民纲领党获得显著优势。

Mr Tusk campaigned on strong economic growth
Initial results suggest Mr Tusk's centre-right party won almost 10% more than its conservative challenger, the Law and Justice Party.

Opposition³ leader Jaroslaw Kaczynski has admitted defeat.

Civic Platform would be the first Polish party to win two consecutive⁴ terms since communism's fall in 1989.

The official results from Sunday's election are due to be published on Monday.

'Poland first'

An exit poll by TNS OBOP for national TV indicates that Mr Tusk's party won 39.6% of votes, comfortably ahead of the Law and Justice party - which gained 30.1% - but short of an absolute majority.

Mr Tusk said he would work on forming a governing coalition⁵ on Monday.

He is expected to renew his alliance with his current partner, the Peasants' Party, which has said it is willing to team up with the Civic Platform again if an offer is made.

The party won 8% of the vote, according to the exit polls.

A new left-wing party, Palikot's Movement, appears to have won a surprise 10% of votes, while the Democratic Left Alliance has won 7.7%, according to the initial TNS OBOP poll.

Mr Tusk, 54, appears to have been rewarded for presiding over four years of strong economic growth, since winning a snap election in 2007.

Poland has been the only EU member state to avoid recession and this year its economy is forecast to grow by about 4%, the highest rate among the EU's seven largest economies.

He campaigned on his economic success and also vowed⁶ to pursue a steady rapprochement with Russia, despite rows over missile defence and gas pipelines⁷ as well as the conduct of an inquiry⁸（调查） into a plane crash that killed Poland's president last year.

"It is the highest honour for me and for Civic Platform that we will be working for the next four years for all of you, regardless of who you voted for today," Mr Tusk told supporters on Sunday.

"In the next four years we will work twice as hard," he said, according to AP news agency.

The Law and Justice Party's Jaroslaw Kaczynski is known for his mistrust of the two countries which invaded Poland during World War II, Germany and the USSR. He also attracts support from Polish Eurosceptics.

"We remain convinced that Poland wants major change," Mr Kaczynski said. "We need to convince millions of Poles. Our day of victory will come."

The 62-year-old served as prime minister from 2005 to 2007, with his twin brother, Lech, as president. Lech Kaczynski died in a plane crash with 95 others in April 2010.

Jaroslaw Kaczynski competed in the snap presidential polls which followed, but lost to Tusk ally Bronislaw Komorowski.

The voting turnout was 47.7%, TNS OBOP said.
