Chega Now Holds Power in Four of Portugal's Five Largest Municipalities

Less than five months after local elections in which its best result was winning the 60th-largest municipality in the country, Chega has manoeuvred itself into governing coalitions in four of Portugal's five biggest cities. The rapid expansion of the party's local influence marks one of the most significant shifts in Portuguese municipal politics in recent memory.

Lisbon, Sintra, Vila Nova de Gaia, and Cascais -- home to more than 15 per cent of Portugal's population -- now have Chega-elected councillors participating in their executive governments. Only Porto remains without Chega involvement in the ruling coalition.

How It Happened

The path began in October, when PSD-led coalitions (variously including CDS, Iniciativa Liberal, and PAN) won all five municipalities but fell short of outright majorities. That arithmetic created an opening that Chega has exploited with remarkable speed.

Sintra was the first domino to fall. Mayor Marco Almeida negotiated a governance agreement with Rita Matias, Chega's local leader, prompting the national leadership of Iniciativa Liberal to withdraw confidence from its own councillor, Eunice Baeta, for not distancing herself from the arrangement. "In democracy, there are no first-class and second-class votes," Almeida defended.

Lisbon and Cascais followed with similar dynamics, as PSD-led administrations concluded that stable governance required working with the councillors voters had elected under the Chega banner. The arrangements have not been universally welcomed within the winning coalitions, with CDS figures in particular expressing discomfort.

A Pattern With National Implications

The municipal-level normalisation of Chega's participation in governance carries weight beyond city hall. At the national level, the party remains in opposition, but its growing footprint in local government provides a platform for demonstrating administrative competence -- or, critics would argue, for entrenching positions that will be difficult to reverse.

For the diverse communities that make up these municipalities -- including substantial immigrant populations in Lisbon, Sintra, and Cascais -- the question is whether Chega's participation will translate into meaningful policy shifts at the local level. Housing, integration services, and cultural programming are among the areas where councillors can exercise real influence, and the party's positions on immigration have historically been contentious.

The coalition tensions also highlight a broader challenge for Portugal's centre-right: how to govern without absolute majorities in an era of fragmented politics. The pragmatic embrace of Chega at the local level sits uneasily with the firewalls some parties maintain at the national level, creating a dissonance that voters and commentators are increasingly noting.
