WARSAW, Oct 21 (Reuters) - Poland's Civic Platform, poised to form the next government after winning Sunday's parliamentary election, said it would seek to pull out Polish troops from Iraq in 2008. "Polish troops should withdraw from Iraq in 2008 because our mission has already been fulfilled," Bogdan Zdrojewski, head of the party's parliamentary caucus, told Reuters by telephone. He said the centre-right party could break the outgoing government's negotiations with the United States on hosting a missile defence system on Polish soil unless Washington offered sufficient security trade-offs.
