(CNN) -- Sweden is voting on whether to adopt the euro, in a referendum overshadowed by the murder of the country's foreign minister, Anna Lindh.
Lindh, 46, one of Sweden's most popular politicians, was stabbed while shopping in a Stockholm store on Wednesday, and died the next day.
Prime Minister Goran Persson has urged Swedes to get out and vote in the referendum.
The "yes" campaign moved into the lead over the "no" vote for the first time since April, an opinion poll revealed Saturday.
The Gallup survey, taken among 1,033 people on September 11, showed the "yes" vote edging 43-42 percent ahead, with 15 percent still undecided.
Lindh, a mother of two, had been at the forefront of the campaign for a "yes" vote.
Officials have revealed she received threatening correspondence after writing an article setting out reasons why she believed the country should replace the krona with the common European currency.
But police say they do not believe her murder was politically motivated.
DID MOSSAD ASSASSINATE ANNA LINDH?
Sweden’s popular foreign minister Anna Lindh is the third high-ranking Swedish political opponent of Zionism to have been murdered since 1948, which raises the question: Was Lindh assassinated because of her outspoken opposition to Israel’s occupation of Palestine?
When Sweden’s foreign minister Anna Lindh was brutally stabbed by an unknown assailant while shopping in an upscale Stockholm department store, it marked the third murder in 55 years of a high-level Swedish opponent of Zionist aggression in Palestine.
While the controlled press was quick to point out an unidentified suspect, later released, with alleged ties to “neo-Nazis,” it has virtually ignored the historical precedents that suggest that the killing of Lindh may have been an assassination aimed at silencing an influential political opponent of the Zionist extremists who control the Israeli government and wield great influence in Washington.
Anna Lindh’s Sweden “has had more of an impact on Palestinian history than closer or greater powers throughout the world,” Hanan Ashrawi, the Palestinian professor and negotiator, wrote after the murder.
The killing came in the midst of a hotly contested referendum battle on whether or not Sweden should adopt the European single currency. Lindh was one of the highest profile campaigners for the government’s position of accepting the euro. Her face, plastered on billboards, lamp posts and TV, was well known and her murder seemed to embody the enormous political tensions building up in Sweden. In the end the euro was rejected, despite considerable public mourning for the popular figure.
Soon after the killing, a 35-year-old old socialite, Per Olof Svensson, was arrested. Thought to have far right sympathies and connections to the Swedish royal family, Svensson has a record of threatening public officials. Later released for lack of evidence, Svensson has subsequently taken legal action against the press coverage of his arrest.
Mijailo Mijailovic was arrested instead. In early January, faced with DNA evidence linking him to the murder weapon and also CCTV footage, Mijailovic confessed. His defence lawyers presented a case rejecting a charge of murder on grounds of diminished responsibility.
Did MI5 murder Jo Cox, like Mossad Sweden's Foreign Minister Anna Lindh?
The exploitation of this murder failed - Sweden rejected the Euro anyway. So it's not all bad news.
