The June survey of 1,022 people found 56.9 percent in favor of adopting the single European currency, 36.2 percent against and 6.9 percent undecided.

It confirmed other polls that found Danes favorably inclined towards the euro since it became the single currency for 12 European countries on January 1, 2002.

In September 2000, 53 percent of Danes rejected the euro in a referendum.

Britain, Denmark and Sweden all belong to the European Union (EU) but not to the euro zone.

The Green poll also found 54.3 percent of those surveyed believed Denmark should cooperate in a common European defense. Opposition was voiced by 26.5 percent and 19.2 percent were undecided.

In 1992 Denmark obtained four exceptions from European policies following its rejection of the Maastricht treaty in a referendum.

They included the single currency, collective defense, judicial cooperation and European citizenship.

The latter refers to issues of reciprocity between Europeans, such as being able to vote or stand for election in municipal and European elections in any EU state.

Denmark's current liberal-conservative government backs lifting the exemptions but has not decided to hold another referendum yet, preferring to wait for the results of a 2004 EU intergovernmental conference and a new Union treaty.
