The Sweden Democrats polled 9.4 percent, a drop of 1.8 percentage points while the Green Party is favoured by 10.4 percent of those surveyed.
Seeking a third consecutive win and with around six months to go before the election, the centre-right coalition is still lagging behind the opposition red-green block, according to the Aftonbladet/United Minds poll. The Social Democrat, Left and Green parties would together have a majority of 50.3 percent if the election were held today, a lead of 12.7 percent over the Alliance.
"The gap is larger now than it was at the same time four years ago. At the same time, I believe that the Alliance is able to catch," says opinion analyst Felix Åberg at United Minds in Aftonbladet.
"The election campaign has not really started yet and Alliance voters are less mobilized.So I think it will benefit the government when the options crystallize clearer," says Felix Åberg.
The poll suggests that the Centre Party would make it over the four percent threshold for parliament but the fellow Alliance partner, the Christian Democrats, would not. The biggest party in opposition, the Social Democrats, gained 1.8 percent and moved up to 33 percent of voter support, according to the Aftonbladet/United Minds survey, which was conducted with 1 098 voters between 10 February and 9 March 2014.
