RIO DE JANEIRO (Reuters) - Right-wing Brazilian presidential candidate Jair Bolsonaro vowed to support the sale of assets by state-run oil company Petroleo Brasileiro SA on Sunday, as he received the official confirmation of his candidacy by his party's convention.

Bolsonaro is leading early opinion polls ahead of October elections, with leftist Ciro Gomes challenging the more moderate Marina Silva for second place. The numbers exclude jailed but still popular ex-president Luiz Inacio Lula da Silva..
