Voting for the presidency is in full swing in Brazil, Latin America’s largest nation.
Voters are choosing between far-right Congressman Jair Bolsonaro and former Sao Paulo Mayor Fernando Haddad.
Polls ahead of Sunday’s vote showed Mr Bolsonaro with a 10-point advantage. But the race appears to be tightening, as just weeks before he had an 18-point lead.
During the first round of voting on October 7, Mr Bolsonaro secured 46% compared to 29% for Mr Haddad.
Mr Bolsonaro has promised to crack down on crime and overhaul the economy.
Mr Haddad has promised a continuation of many progressive policies of his Workers’ Party, which governed from 2003 to 2016.
