The state run Statistics Sweden survey showed that the centre-right Alliance parties would win between 47.7 and 50 percent of votes if the election were held today. The ruling left-wing bloc would have the support of between 46.7 and 49.1 percent.
The gap between the two blocs has never been as small in the May month prior to a September election.
The pollsters interviewed a random sample of 9,331 people, of which 17.3 percent did not answer. People were asked the question: ”Which party would you vote for if there was a general election in the next few days?”.
