Mayor before election Xavier Trias CiU Elected Mayor Ada Colau BComú

A municipal election was held in Barcelona on Sunday, 24 May 2015, to elect the 10th City Council of the municipality. All 41 seats in the City Council were up for election. It was held concurrently with regional elections in thirteen autonomous communities and local elections all throughout Spain.

The election was won by the Barcelona en Comú (BComú) citizen platform, supported by Podemos, Initiative for Catalonia Greens–United and Alternative Left (ICV–EUiA) and Constituent Process (Procés Constituent) and led by Ada Colau popular activist and former spokeswoman of the Platform for People Affected by Mortgages (PAH). Incumbent mayor Xavier Trias of the Convergence and Union (CiU) federation, who had campaigned for a second consecutive term in office, saw his support reduced from 14 to 10 out of 41 seats in the council. Citizens (C's) became the third largest political force in the city, whereas Republican Left of Catalonia (ERC) obtained its second best historical result. On the other hand, both the Socialists' Party of Catalonia (PSC) and the People's Party (PP) were severely mauled. The PSC, which had won every municipal election in Barcelona and had controlled the local government up until 2011, fell to fifth place and below 10% of the share, while the PP achieved its worst result since the People's Alliance (AP) result in the 1987 election. The Popular Unity Candidacy (CUP) also entered the City Council for the first time in history, winning 3 seats and 7.4% of the votes.

Colau went on to become the first female mayor of Barcelona in history with the support of the BComú, ERC, the PSC and one of the CUP councillors. ^[1]

Overview

Under the 1978 Constitution, the governance of municipalities in Spain—part of the country's local government system—was centered on the figure of city councils (Spanish : ayuntamientos), local corporations with independent legal personality composed of a mayor, a government council and an elected legislative assembly. ^{[2] [3]} In the case of Barcelona, the top-tier administrative and governing body was the City Council of Barcelona. ^[4]

Electoral system

Voting for local assemblies was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered and residing in the municipality of Barcelona and in full enjoyment of their political rights (provided that they were not sentenced—by a final court ruling—to deprivation of the right to vote), as well as resident non-national European citizens and those whose country of origin allowed Spanish nationals to vote in their own elections by virtue of a treaty. ^{[3] [5] [6]}

Local councillors were elected using the D'Hondt method and a closed list proportional voting system, with an electoral threshold of five percent of valid votes (which included blank ballots) being applied in each municipality. ^[7] Each municipality constituted a multi-member constituency, entitled a number of seats based on the following scale: ^[8]

Population	Councillors
<100	3
101–250	5
251–1,000	7
1,001–2,000	9
2,001–5,000	11
5,001–10,000	13
10,001–20,000	17
20,001–50,000	21
50,001–100,000	25
>100,001	+1 per each 100,000 inhabitants or fraction +1 if total is an even number

The law did not provide for by-elections to fill vacated seats; instead, any vacancies that occurred after the proclamation of candidates and into the legislative term were to be covered by the successive candidates in the list and, when required, by the designated substitutes. ^[9]

The mayor was indirectly elected by the local assembly. ^[3] A legal clause required candidates to earn the vote of an absolute majority of councillors, or else the candidate of the most-voted party was to be automatically appointed to the post. In the event of a tie, the appointee was to be determined by lot. ^[10]

Election date

The term of city councils in Spain expired four years after the date of their previous election, with election day being fixed for the fourth Sunday of May every four years (as of 2025, this has been the year before a leap year). ^[11] Local councils could not be dissolved before the expiry of their term, except in cases of mismanagement that seriously harmed the public interest and implied a breach of constitutional obligations, in which case the Council of Ministers could—optionally—agree to call a by-election. ^[12]

Elections to local councils not bound to the open council system were officially called on 31 March 2015 with the publication of the corresponding decree in the BOE, setting election day for 24 May. ^[13]

Parties and candidates

The electoral law allowed for parties and federations registered in the interior ministry, alliances and groupings of electors to present lists of candidates. Parties and federations intending to form an alliance ahead of an election were required to inform the relevant electoral commission within ten days of the election call, whereas groupings of electors needed to secure the signature of a determined amount of the electors registered in the municipality for which they sought election, disallowing electors from signing for more than one list of candidates. In the case of Barcelona, as its population was over 1,000,001, at least 8,000 signatures were required. ^[14] Additionally, a balanced composition of men and women was required in the electoral lists, so that candidates of either sex made up at least 40 percent of the total composition. ^[15]

Below is a list of the main parties and electoral alliances which contested the election:

Opinion polls

The tables below list opinion polling results in reverse chronological order, showing the most recent first and using the dates when the survey fieldwork was done, as opposed to the date of publication. Where the fieldwork dates are unknown, the date of publication is given instead. The highest percentage figure in each polling survey is displayed with its background shaded in the leading party's colour. If a tie ensues, this is applied to the figures with the highest percentages. The "Lead" column on the right shows the percentage-point difference between the parties with the highest percentages in a poll.

Voting intention estimates

The table below lists weighted voting intention estimates. Refusals are generally excluded from the party vote percentages, while question wording and the treatment of "don't know" responses and those not intending to vote may vary between polling organisations. When available, seat projections determined by the polling organisations are displayed below (or in place of) the percentages in a smaller font; 21 seats were required for an absolute majority in the City Council of Barcelona.
