The Swedish People's Party MP received several comments threatening her with violence following her appointment and subsequent policy statements.
Earlier this week, Thors pledged that Finland would have a more active immigration policy. She noted that the new government's platform includes several steps aimed at making it easier for foreigners to settle in Finland.
The portfolio Thors holds is a new one, comprised of areas of responsibility formerly overseen by the ministers of labour and the interior.
Thors, 49, is a Helsinki lawyer and former Member of the European Parliament. She is the former chair of the Finnish Unicef organisation, and is stepping down as chair of the Finnish Refugee Advice Centre.
