Support among Swedes for membership of the EU's common currency leapt after the murder of Foreign Minister Anna Lindh.
Euro supporters are now neck-and-neck with their opponents, an opinion poll showed today.
Research institute SKOP's survey of 792 Swedes made after Ms Lindh's death yesterday morning gave the pro-euro "Yes" side 50 per cent support against 50 per cent for the anti-euro "No" camp.
SKOP said in a statement the poll yesterday compared to an unpublished poll it had made on September 9th-10th, before the attack on Ms Lindh, on 1,103 people in which 42 per cent would vote for the euro and 58 per cent against.
SKOP did not give the number of the undecided in either survey. On Sunday Sweden will hold a referendum on whether to join the euro.
Until now, euro opponents have been ahead in every opinion poll since April. Political scientists said yesterday the killing of Ms Lindh could spark a wave of sympathy for the "Yes" side, for which she had been campaigning.
