Polish prime minister's return relief for markets, no panacea

WARSAW, Poland - Victory for Polish Prime Minister Donald Tusk's ruling center-right Civic Platform (PO) in Sunday's election brings relief to jittery financial markets but they will soon demand action on cutting the budget deficit and debt.

Tusk's PO won nearly 40 percent of the vote, exit polls showed, many more than its nearest rival, Jaroslaw Kaczynski's nationalist-conservative Law and Justice party, and is expected to renew its coalition with the small Peasants' Party.

Tusk swiftly claimed victory and Kaczynski conceded defeat, though final results are not expected until Tuesday evening.
