Stockholm - The Swedish parliament ratified the European Union reform treaty late Thursday after a nine-hour debate.
The Lisbon Treaty was approved by 243 legislators while 39 voted against. Thirteen members of the 349-seat legislature abstained while 54 members did not attend the vote.
EU Affairs Minister Cecilia Malmstrom, who had urged legislators to ratify the treaty, said it contained "new rules" and offered a "more efficient and open EU."
Rejecting the treaty would mean that Sweden would have "poorer means of influencing decisions" and would lose its say, Malmstrom said.
Birgitta Ohlsson, member of Malmstrom's Liberal Party, earlier said the treaty would make the EU more up-to-date.
