Less than one in three in Sweden wants to say farewell to the krona as swapping to the euro would hurt the economy.

• Swedish krona soars as the euro suffers
• Oil-rich Norwegians turn their backs on EU

Eurozone public debt crisis -- especially in Greece -- and growing economic tensions make less than one third of the Swedes wanting to join EU's economic and monetary collaboration and introduce the euro.

Only 29 percent of Swedes would support the introduction of the euro if there was a referendum tomorrow, according to a new poll by Novus Opinion.

Sweden joined the EU in January 1995 but turned down the euro in a 2003 referendum.

On Monday the euro fell to its lowest point in four years over fears about eurozone dept problems. The financial crisis has led many Swedes to think that the single European currency wouldn’t benefit Sweden. Almost half of those polled fear that the eurozone crisis will have negative effects on the Swedish economy.

The poll clearly shows a shift in opinion. In April almost half of the polled (47 percent) said they were in favor of saying farewell to the krona and swap to euros.

Norway is also turning their back to the EU collaboration. Less than one third of Norwegians favour joining the European Union, a survey published a week ago showed, as the debt crisis in Greece and other EU countries dominated headlines.

"It is clear that what is currently happening in Europe has caught Norwegians' attention," Heming Olaussen, who heads the No to EU organisation, told NRK.
