SAO PAULO (AP) — Brazilian senator Flávio Bolsonaro, a son of former President Jair Bolsonaro, was confirmed as the presidential candidate of his father's Liberal Party on Saturday in a bid against incumbent President Luiz Inácio Lula da Silva, even as his campaign faces many challenges.

The younger Bolsonaro still seeks a running mate and does not enjoy the support of centrist parties as his father did. Few Brazilian political heavyweights were in attendance, in another sign of his troubles forming an alliance against Lula ahead of the October election .
