Balbo took leave from her university career and ran for parliament, gaining her first seat in 1983. She remained in parliament until 1992 as an independent and later as part of
Sinistra indipendente (the Independent Left). She subsequently joined
Verdi (the Greens). She was asked by
Massimo D'Alema to take on the role of Minister for Equal Opportunities from 1998 to 2000. She instigated efforts to expand the remit of equal opportunities to encompass discrimination on the basis of race and sexual orientation discrimination. For the first time in Italy, the issue of sexual orientation became the subject of a specific assignment in the Ministry, in the person of
Franco Grillini. She also worked to strengthen women's representation in politics and improve female employment, including organising the first national conference on female employment in Naples in January 2000, opened by President
Carlo Azeglio Ciampi. Between 2000 and 2001, she was a special advisor to the Prime Minister on issues of discrimination and racism. ==Death==
