In a statement to the Expressen newspaper, party secretary Hannes Hervieu said that his party was ready to build a "strong and effective government" with the Social Democrats if the opposition parties retain their lead over the four right-wing parties.
Hervieu reiterated his party's reluctance to join a government that includes the so-called 'fringe parties', or ytterkantspartier, which include both the far-right Sweden Democrats and the Left Party.
"If this is the election result, then the Social Democrats need to see the big picture," he wrote. "Because it clearly shows that voters neither want to see an economic leftward turn, nor major influence for the Sweden Democrats."
"There is no demand for fringe politics, but rather a desire for political stability and a political content with a clear centre-right character."
Senior Social Democrats welcomed the Centre Party's statement, its first clear sign of its intentions since the opposition started to look set for a narrow victory.
"It is positive that they are willing to take responsibility for the election results we seem to have received right now," the party's justice spokesperson, Teresa Carvalho, said. "If it holds, then Ulf Kristersson should resign and Magdalena Andersson should form a government. It will be positive if others also take responsibility for the election results."
Morgan Johansson, a party heavyweight, warned that the Social Democrats were not ready to cede as much policy to the Centre Party as the party did in the January Agreement in 2019.
“The compromises we made in the January 2018 agreement look like they're likely to be greater than what we would need to make this time,” he said.
In his election night speech, Prime Minister Ulf Kristersson stretched out a hand to the Centre Party, pointing out that there is a "non-Socialist majority" in Sweden which could still potentially form a government.
