All candidates for the 2018 Brazilian presidential elections on Thursday began campaigning on the streets across the country, except the former president Luiz Inacio Lula da Silva, who is serving a 12-year prison sentence for corruption, and had to resign himself to launching his proclamations on social networks.

The race for the October 2018 presidential elections to find President Michel Temer's successor on Thursday moved to a new phase in which candidates can publicly rally for votes, disseminate electoral propaganda on the streets and post messages on social networks.

Seven of the 13 candidates participated Thursday in a meeting organized by the Women's Group of Brazil in Sao Paulo - the country's largest electoral college - in which they defended a greater inclusion of women in leadership spaces.

Uncertainty over Brazilian politics still revolves around the situation of Lula, whom the Workers' Party (PT) registered the day before as its official candidate despite his ineligibility since he was convicted on corruption charges in an appeals court.

The prosecution on Wednesday filed an objection against Lula's candidacy before the electoral court, while the PT's former Education Minister and former mayor of Sao Paulo, Fernando Haddad, on Thursday called on the court to expedite a resolution on Lula's eligibility.

In spite of the ambiguity of his future in Brazilian politics, Lula still tops the opinion polls in what could be his sixth time as a presidential candidate, and his advisers had to resort to social media to campaign for him instead.
