The tour will take place in the four northernmost counties and last nine days. Löfven will take part in most of it.
We are doing this because we think all of Sweden is important, says party secretary Tobias Baudin, who will also accompany us on the tour.
On Sunday, the Social Democrats will present their election poster campaign with the message "Time to take Sweden seriously."
It's about not letting populism take over, says Baudin.
There are also local versions of the posters, for example "Time to take Östergötland seriously".
