Wallström is one of the most popular politicians in the Swedish Social Democrats, and in fact in Sweden. An opinion poll in the beginning of January, put her as a clear favourite to be the country's next prime minister - ahead of the conservative current prime minister Fredrik Reinfeldt, and ahead of the leader of the Social Democratic party, Mona Sahlin.
Wallström herself, however, has always said she will not go back to politics in Sweden after finishing her job at the European Commission in just over a week's time. How the new job affects her contribution to the upcoming election campaign is not clear. Wallström has said she will want to contribute, but more take on a background role.
