Projections are expected as of 10 pm local time (12 am Monday Occupied Jerusalem Time) after polls in the Azores archipelago. Official results will be published at a later time.

The Socialist Party scored an unprecedented victory in the 2017 vote, as it received 38% of the votes, while its main opposition, the center-right Social Democratic Party, received 28% of the votes.

The elections saw the Socialists winning 161 mayoralties and the Social Democratic Party winning 98.

Rui Rio, the center-right party's leader, announced that he would resign if his party suffered a defeat as severe as that of 2017.

The Socialists will retain Lisbon with ease, according to polls. The city's mayor, Fernando Medina, is pulling ahead of his opponent Carlos Moedas.
