The small left-wing party Partido Socialismo e Liberdade (PSOL) decided on 7 March to reject a proposal to join a party federation with the ruling Partido dos Trabalhadores (PT) of President Luiz Inácio Lula da Silva. A federation is akin to a temporary, partial merger of parties in which each party would retain its own membership and identity but would be able to share election campaign resources and act as one bloc in congress. The rejection of the federation marks a blow to a prominent member of PSOL, Guilherme Boulos, who is currently serving as the secretary general of the presidency and is reportedly a staunch advocate of presenting a more united front among Brazil’s left-wing parties.
