Marina Helou, a state deputy in São Paulo and one of the founders of Rede Sustentabilidade, has announced her departure from the party after 12 years to join the Brazilian Socialist Party (PSB). Helou's decision comes amid a growing exodus of leaders associated with Environment Minister Marina Silva, who is also expected to leave Rede. The discontent among group members stems from feeling constrained by the current leadership, which they perceive as overly authoritarian and unresponsive to their concerns.

In a statement, Helou expressed her emotional struggle in leaving the party she helped establish, acknowledging the difficulty of her decision both personally and structurally. She highlighted that the relationship with the party's direction has reached a point of irrationality, leading her to prioritize constructive contributions to society over futile internal disputes. Helou's commitment to public policy development is underscored by her assertion that it no longer makes sense to invest her energy in a party that does not align with her values.

By joining the PSB, Helou signals a significant shift in her political alignment and indicates the potential for a broader reconfiguration within Brazilian political dynamics, especially among the supporters of environmental policies. This move could also establish a platform for her candidacy for federal deputy, reflecting a strategic repositioning as she seeks to engage with policies that resonate more with her constituents and philosophical beliefs.
