Brazilian President Luiz Inácio Lula da Silva formally launched his candidacy for October's election on Sunday, winning the endorsement of his Workers' Party at a convention in São Paulo attended by around 3,000 people. Lula, 80, said he was 'in great shape' and highlighted his stamina and good health as he seeks what is expected to be his final term in office. The campaign is shaping up to be unusually internationalized, with concerns over foreign influence and pressure from the administration of US President Donald Trump looming over the race. Lula, a leftist titan of Latin American politics who is loved and despised in near-equal measure in Brazil, is running for a fourth term as president.
