"I don't feel that there has been any dramatic shift that changes the fundamental starting point," he says.
Strömmer says the Tidö parties have a lot in common with the Centre Party on policy, in addition to their shared attitude towards the SD.
There is a lot that unites the parties on the right. And if you take that as a starting point, there are of course openings, but then everyone knows that that is not where the deadlocks have been, he says.
According to Strömmer, the deadlock lies in the Centre Party's red line against the SD.
Exactly how it would be resolved, and whether it would be possible at all, is a question largely owned by the parties themselves.
Earlier on Sunday, SD leader Jimmie Åkesson issued an open letter to Centre Party leader Elisabeth Thand Ringqvist, inviting her to talks even though she had ruled out cooperation with the SD. At the same time, Åkesson reiterated the SD's position that it would either be in government or in opposition. How Thand Ringqvist will respond to the invitation is not known.
On Monday, the Speaker will hold a press conference on how the process of forming a government will proceed, after Magdalena Andersson was voted down as a candidate for prime minister in the Riksdag chamber last week.
