Four political parties held official conventions in Belo Horizonte on Monday, July 20, 2026, to nominate candidates for the upcoming elections [1].

These meetings are critical because they serve as the legal mechanism for parties to formalize candidate selections and finalize coalition agreements. Under Brazilian electoral law, these conventions are the only official way to validate who will represent a party on the ballot.

The events on Monday marked the first day of the official convention calendar [1]. Parties have until Aug. 5, 2026, to complete these gatherings [1]. This window allows political organizations to negotiate alliances and ensure their candidate lists meet legal requirements before the final registration phase.

Following the conclusion of the convention period, parties must meet a strict deadline for candidate registration on Aug. 16, 2026 [2]. This process ensures that all nominees are properly documented with the electoral courts.

Campaign activities are also set to begin shortly. The official start of campaign activities is scheduled for July 21, 2026 [2]. This transition from internal party nominations to public campaigning marks a shift in the political landscape of Minas Gerais.

While the specific names of the four parties were not detailed in the initial reports, the gatherings in Belo Horizonte represent the primary coordination point for regional political strategy. These meetings determine the viability of various coalitions, and the distribution of party resources for the 2026 cycle [1].

The commencement of party conventions in Minas Gerais signals the transition from private political negotiation to public electoral competition. By formalizing coalitions and candidates now, parties are locking in the strategic alliances that will define the 2026 race, leaving little room for last-minute pivots before the August registration deadline.
