Former President Michelle Bachelet says she will run again for Chile's top office in November elections as the candidate of the country's center-left and communist party.

Bachelet returned to Chile on Wednesday after ending a two-year stint heading the U.N. women's agency in New York.

The former president told cheering supporters in a poor Santiago neighbhorhood that "I have taken the decision to be a candidate."

Bachelet is widely seen as the center-left opposition's only hope of winning the Nov. 17 presidential election.

Bachelet, 62, said that inequality is the main problem facing Chile.

Candidates must to be ready to tackle mounting social demands and frequent protests that troubled Bachelet during her 2006-2010 presidency and that have harried center-right President Sebastian Pinera even more.
