Against a fractured opposition, Fernando Medina, mayor since the resignation of António Costa in 2015, was elected for a full term, defeating Assunção Cristas (CDS-PP leader) and Teresa Leal Coelho (PSD).

[1] Despite the victory, the Socialist Party lost its majority by one seat, having to rely of the Left Bloc's support.

[2] The Unitary Democratic Coalition presented former MEP João Ferreira again and achieved similar results, and that guaranteed two Communist councilors.

The Left Bloc, with Ricardo Robles as the candidate for Mayor, managed to gain a councillor seat for the first time in 10 years.

The PSD-CDS coalition led by Fernando Seara got about 22 percent of the votes, the worse result for the center right ever in Lisbon.
