The election was also marked by the strong electoral performances of various independent groups, which won several chambers. The most significant was the victory of independent Rui Moreira in Porto, who was supported by CDS-PP. The Democratic Unity Coalition increased its number of municipal chambers as well as its number of councilors by winning several chambers previously held by the Socialists, including winning back their historical stronghold of Loures. However, despite increasing their overall number of mayors, they also lost three chambers they won in 2009 to the Socialists; Chamusca, Crato, and Nisa. In Chamusca they had held the mayorship since 1979.
