(COPENHAGEN) - Denmark's parliament voted by a large majority on Thursday to ratify the European Union's Lisbon Treaty to revamp decision-making in the 27-member bloc.

The Folketing voted 90-25 in favour of adopting the treaty, with no abstentions.

In a statement in Brussels, European Commission chief Jose Manuel Barroso welcomed the vote in Denmark, where one EU treaty foundered in the past, and thanked both the parliament and the government.

"Denmark is the 10th member state to complete the parliamentary process of approval of the treaty. The ratification process is well advanced in the other member states and I look forward to its successful conclusion," he said.

The Lisbon Treaty, negotiated under Portugal's EU presidency and signed in the Portuguese capital, is aimed at streamlining decision-making, and replaces the EU constitution rejected by French and Dutch voters in referendums in 2005.

All 27 member states must ratify the treaty for it to be enacted, which the bloc hopes to achieve by the end of the year so that the issue does not interfere with campaigning during elections to the European Parliament in 2009.

Ireland is the only EU country which will put the treaty to a referendum.

Denmark was granted four exemptions from the EU in December 1992 -- on the euro single currency, defence policy, judicial cooperation and European citizenship -- after citizens rejected the Maastricht Treaty in a referendum.

The opt-outs enabled the government to organise another plebiscite in May 1993, after which the treaty was adopted.

On Tuesday, Danish Prime Minister Anders Fogh Rasmussen said the government may call a referendum later this year -- perhaps in the European autumn -- on one or several of its exemptions.

According to the commission, the Lisbon Treaty has now been approved by the parliaments of Denmark, Hungary, Malta, Slovenia, Romania, France, Bulgaria, Poland, Slovakia and Portugal, which did so on Wednesday.

However Poland's must be signed by its president to be formally adopted.
