The poll asked voters who they would vote for if the elections for Parliament were held today.
The Social Democrats, the largest political party, increased their support by 3.4 percent to 32 percent. Support for the Sweden Democrats increased by 3.7 percent to 16 percent.
Every other party lost support and the biggest loser was the conservative Moderate Party, which had led the government for eight years prior to getting defeated in September's elections. They went down 2.1 percent to land at 23.7 percent support.
Though they have not been officially called yet, extra elections are planned for March 22, a decision the Prime Minister made after his Social-Democratic-led government's budget failed to pass in Parliament.
