But we have always been on the side of vulnerable people and it must become much clearer to the voters ", she writes in the debate article.
Lindhagen has previously announced that she "strongly considers" running after the news that the mouthpiece Isabella Lövin chooses to leave politics.
Member of Parliament Rebecka Le Moine and one of the party's group leaders Annika Hirvonen are also candidates for the post, as are the other group leader Janine Alm Ericson and party secretary Märta Stenevi. The new mouthpiece will be elected at an extra congress at the beginning of next year.
