In the opinion poll by Demoskop, the Social Democrats, the Left Party and the Greens have a combined 48.8% support compared to 47.9% for the Alliance.
The ratings, published by TV4 and Expressen, show that the Left Party has made the greatest stride forward, increasing its support from 5.2% to 7.1%. The Greens have picked up more support too, climbing to 5.5%, while the Social Democrats have declined slightly, to 36.2%.
The Centre Party is the big loser, and if the election were held today the party would not even get into parliament. With only 3.6% support, it falls short of the 4% required for a party to be able to claim its parliamentary place.
The Christian Democrats are teetering too, on 4% support, while the Moderates and Liberals are almost unchanged, on 30.3% and 10.0% respectively.
With five months until the election, many voters are still unsure of which party will get their vote.
The Moderates have the most secure supporters, according to a poll by Synovate Temo published on Thursday in Dagens Nyheter. 89% of Moderate Party supporters are sure of their decision, while the same amount are certain that they will vote on the big day.
Social Democrat supporters are less sure. Indeed, 20% say that they are not sure if they will actually vote for their current favourites.
In total, 83% of the conservative bloc’s supporters are certain of their choice, compared to 77% of the left wing coalition’s supporters.
