Brazil’s new president, Michel Temer, has been named leader of the country’s new ruling party.
In his first interview since assuming office in May, Temer told reporters he has no plans to withdraw from office.
He has said he is committed to the “principles of a free society” and that his government will continue to respect the rule of law.
The president also said he will continue his campaign against corruption.
“This is a new day for Brazil,” Temer said.
“This is an era of change.”
The country’s former president Luiz Inacio Lula da Silva is also being congratulated for his victory.
But Rousseff, who has faced criticism from international organisations for her role in Brazil’s slow economic recovery, is still popular in Brazil.
The next presidential elections are due in 2018.
