The new poll, carried out by Demoskop for the Svenska Dagbladet newspaper promises to energise the right-wing bloc by showing that they still have everything to fight for as they enter the final month of the campaign ahead of the election on September 13th.
"Now the match begins," Martin Borgs, who is running the Moderate Party's campaign, told the newspaper, claiming that more and more voters were realising that a win for the opposition would hit their wallets.
The Social Democrats' party secretary Tobias Baudin told the paper he was not worried about the left bloc's narrowing lead.
"Not at all. Our election campaign is going according to plan and we feel a huge amount of confidence," he said. "Our focus is on election day. There will be many different polls coming up."
"It's a huge difference psychologically, at least for the parties, if there's a difference of around 8 or around 4 percentage points between the blocs," Johan Martinsson, head of opinion at Demoskop, said.
In the new poll, the Moderates, Christian Democrats, Liberals, and Sweden Democrats together won the support of 46.9 percent of respondents while the Social Democrats, Centre Party Green Party and Left Party had a slim majority of 50.6 percent.
As the Liberal Party is still under the parliamentary threshold of four percent, however, this percentage would only give the government parties 163 parliamentary seats, compared to 186 for the opposition parties.
The poll of 2,106 respondents was carried out between July 29th and August 10th, making it the first poll since the government parties announced a long list of generous election pledges at the Almedalen political festival.
The Christian Democrats, who promised to nearly double child benefit, registered their best result since March 2020, winning the backing of 7.5 percent of respondents, with Demoskop crediting the party with pulling voters over the bloc divide from the Social Democrats and Centre Party.
The only opposition party to see growing support was the Centre Party, which grew from 6.2 percent 7.3 percent, overtaking both the Left Party (down from 7.6 percent to 6.5 percent) and the Green Party (down from 7.6 percent to 6.6 percent).
