RIO DE JANEIRO — Brazil's ruling Workers' Party, or PT, on Sunday officially nominated incumbent President Luiz Inacio Lula da Silva as its candidate for the upcoming presidential election as he seeks a fourth term in office.

At the party's national convention in Sao Paulo, delegates formally approved the ticket pairing Lula with incumbent Vice President Geraldo Alckmin of the Brazilian Socialist Party.

PT President Edinho Silva announced that the party had completed its candidate registration with the Superior Electoral Court.

"This election in Brazil determines the future of Latin America," Silva said during Sunday's convention. Argentina, Paraguay, Chile, Peru, Ecuador and Colombia have elected right-wing, conservative, or populist presidents in the recent past.
