Brazilian President Dilma Rousseff was reelected on Sunday for a second term in office following a closely fought battle.
Sixty-six-year-old Rousseff of the workers' party won 51.6% of the vote in the runoff.
Rival Aécio Neves of the center-right PSDB party secured 48.4%.
Rousseff is set to govern until 2018, after which the workers party will have been in power for 16 years.
She became Brazil's first female president in 2010, succeeding Luiz Inácio Lula da Silva, who served as president from 2003 to 2010 and who has said he might run again in 2018.
