The embattled President Dilma Rousseff yesterday was voted out from office by Brazil’s Senate for manipulating the budget.
This puts an end to the 13 years in power of her left-wing Workers’ Party. Ms Rousseff had denied the charges.
Sixty-one senators voted in favour of her dismissal and 20 against, meeting the two-thirds majority needed to remove her from the presidency.
Michel Temer has been sworn in as president and will serve out Ms Rousseff’s term until 1 January 2019.
The centre-right PMDB party politician had been serving as acting president during the impeachment proceedings. During his first cabinet meeting since the vote, Mr Temer said his inauguration marked a “new era”.
He asked his ministers to “vigorously defend” the government from accusations that Ms Rousseff’s dismissal amounted to a coup d’etat.
“We can’t leave one accusation unanswered,” he said during the meeting, which was broadcast live on television.
He also told ministers to work closely with the Congress to revive the Brazilian economy. Mr Temer is travelling to China to take part in a summit of the G-20 group of major economies.
The dismissal of Ms Rousseff has caused a rift between Brazil and three left-wing South American governments that criticised the move later on Wednesday.
Brazil and Venezuela recalled each other’s ambassadors. Brazilian envoys to Bolivia and Ecuador have also been ordered home.
Ms Rousseff lost the impeachment battle but won a separate Senate vote that had sought to ban her from public office for eight years.
Pledging to appeal against her dismissal, she told her supporters: “I will not say goodbye to you. I am certain I can say: ‘See you soon.'”
She added: “They have convicted an innocent person and carried out a parliamentary coup.”
Anti-Temer demonstrations were held in many cities, including Brasilia.
Ms Rousseff was suspended in May after the Senate voted to go ahead with the impeachment process. She was accused of moving funds between government budgets, which is illegal under Brazilian law.
Her critics said she was trying to plug deficit holes in popular social programmes to boost her chances of being re-elected
Ms Rousseff fought the allegations, arguing that her right-wing rivals had been trying to remove her from office ever since her re-election.
