A little over half of Sweden's voters want a new referendum on whether to adopt the euro as their currency, a survey showed Tuesday. According to Stockholm-based Novus Opinion, 51 percent of 1,000 respondents said they favored a new vote. Forty-four percent were against, while the remainder were undecided. Swedish voters rejected the euro in a 2003 referendum by a 56% margin. But the global financial crisis has rekindled debate about whether Sweden would be better off with the common currency. Supporters say the euro would make the country less vulnerable to currency swings, while skeptics say dropping the krona would eliminate an important tool for controlling the economy.
