I hope that... people around Europe will perceive this as a purely Danish decision

Swedish Prime Minister Goran Persson

"When we get our referendum, nobody will be talking about the Danish referendum," he said.

Along with Britain, Sweden is one of the three countries still outside the euro zone.

Mr Persson had earlier said the outcome would have an impact on the domestic debate in his country.

Split

Giving up the Swedish national currency, the krona, has divided Mr Persson's Social Democratic party, just as it has affected the Labour Party in Britain.

"The result is positive for Sweden, partly because the probability that we can stay outside [the euro zone] increases," said Johan Loennroth of Sweden's former communist Leftist Party.

"But more importantly, it may also have an effect on the entire EMU (European Monetary Union) and the EU," Mr Loennroth, who opposes the euro, said.

The Swedish PM says the outcome will have an impact

His view was echoed by analyst Robert Bergqvist at the Skandinaviska Enskilda Banken in Stockholm

"There is a risk that a "No" in Denmark might be interpreted as a setback for the whole EMU project, he said.

"Then we'll have a world with international concern and in such situations Sweden does not usually manage very well," he added.

Unconcerned

Other European leaders said the vote would not have much of an impact on the European single currency.

French Prime Minister Lionel Jospin, who currently holds the EU presidency, said the Danish economy was not big enough to affect the euro.

"I have a lot of respect for this country but its size for the European economy is not major," he said in Paris.

"I do not think [the vote] will be a problem for a currency which must be a stable currency at the appropriate level," he added.

German Finance Minister Hans Eichel said although it was in Denmark's interest to adopt the euro the rest of Europe would survive the "No" vote.

"Europe will go forward. European integration is a historic process that isn't reversible," he said in Berlin.

"But the earlier one is there, the better," he added.

Eleven countries have adopted the euro thus far.
