Chile's once and future leader Michelle Bachelet has won a presidential runoff, returning center-left parties to power by promising profound social changes in response to years of street protests.
Bachelet won 62 percent of Sunday's vote, the most decisive victory in eight decades of Chilean elections.
Evelyn Matthei, the presidential candidate of Chile's ruling conservative coalition, choked back tears as she conceded defeat, Al Jazeera's Lucia Newman, reporting from the capital Santiago said.
