In the afternoon, the Social Democrats offered to participate in tonight's Agenda.
On Sunday evening, party representatives declined to comment on the government crisis to several media.
"The Prime Minister refuses to comment," writes press secretary Mikael Lindström in a text message to Aftonbladet.
Löfven himself has not made any public statements since Thursday.
By Monday at the latest, he must make a decision to announce by-elections, which in that case will be held in a maximum of three months, or resign.
In the latter case, presidential rounds will be held.
