In Trentino-Alto Adige/Südtirol the elections were held on 15–16 May with a second ballot on 30–31 May; all of 321 comuni of the region voted for a new mayor and a new City Council.
In Italy, direct elections were held in municipalities and provinces: in each municipality (comune) were chosen mayor and members of the City Council, in each province were chosen president and members of the Provincial Council.
The voting system is used for all mayoral elections in Italy in cities with a population higher than 15,000.
This gives a result whereby the winning candidate may be able to claim majority support, although it is not guaranteed.
The election of the City Council is based on a direct choice for the candidate with a preference vote: the candidate with the majority of the preferences is elected.
