BRASILIA (Reuters) - Brazil's President Dilma Rousseff said her first priority in a second term would be political reform, promising to work with Congress on changes that the country demands after winning re-election in a tight Sunday run-off.

Ms Rousseff had called for a popular referendum on political reform after widespread protests in June 2013, but she dropped the issue in the face of stiff resistance from lawmakers.

In her victory speech, she also reiterated her commitment to fiscal discipline and controlling inflation.
