Madrid City Council election, 2015

Electoral system

The number of seats in the Madrid City Council was determined by the population count. According to the municipal electoral law, the population-seat relationship on each municipality was to be established on the following scale:

Additionally, for populations greater than 100,000, 1 seat was to be added per each 100,000 inhabitants or fraction, according to the most updated census data, and adding 1 more seat if the resulting seat count gives an even number. As the updated population census for the 2015 election was around 3,200,000, the Madrid City Council size was set to 57 seats.

All City Council members were elected in a single multi-member district, consisting of the Madrid municipality, using the D'Hondt method and a closed-list proportional representation system. Voting was on the basis of universal suffrage in a secret ballot. Only lists polling above 5% of valid votes in all of the municipality (which include blank ballots—for none of the above) were entitled to enter the seat distribution.

The Spanish municipal electoral law established a clause stating that, if no candidate was to gather an absolute majority of votes to be elected as mayor of a municipality, the candidate of the most-voted party would be automatically elected to the post.

Mayoral Candidates

According to the Spanish legislation on local authorities, the government of cities is assigned to the City Council and the mayor. The Spanish political system is parliamentary democracy in all its levels of government, with the city council responsible for the election of the mayor.

People's Party

The Mayor of Madrid, Ana Botella, announced her intention not to run for mayor in September 2014.

Mariano Rajoy, the President of the PP, designated Esperanza Aguirre as candidate on 6 March 2015.

Spanish Socialist Workers' Party

The Spanish Socialist Workers' Party scheduled a primary election on October 2014. Regional assemblyman and frequent talk show guest Antonio Miguel Carmona and city councillor Enrique del Olmo announced their intention to run for the post. Candidates intending to run had to secure the endorsement of at least 20% of the party membership.

On the closing day of the endorsement collection only Carmona had gathered the required endorsements, thus being nominated as party candidate without the primary election being held.

United Left

United left of Madrid held an open primary election on 30 November 2014. The election was contested by:

Valiente defeated his rivals by securing 59% of the votes. However, he withdrew his candidacy after internal turmoil in the regional branch of the party and entered the Ahora Madrid election list, led by Manuela Carmena. Raquel López was designated as the new IU candidate for the local election instead.

Union Progress and Democracy

The party's current spokesperson on the City Council, David Ortega, obtained a landslide victory (81% of the votes) against three largely unknown candidates.

Electoral campaign

Electoral debates were held in Telemadrid between the candidates of the PP, PSOE, IU, UPyD, Vox, Citizens and Ahora Madrid in the last week of campaign, between 18 and 20 May. The most expected and tense moment came with the debate between PP candidate Esperanza Aguirre and AM Manuela Carmena, as the most-likely candidates to become the next Mayor of the city. Aguirre immediately accused Carmena of saying in the past that "ETA members had suffered a lot", trying to link the former judge with the terrorist group, as well as trying to dicredit Carmena's career in the judiciary, which was seen as a furious attack of Aguirre on Carmena. The latter, visibly surprised, counterattacked responding that Aguirre was acting arrogantly and contemptuous to others and accusing her of allowing corruption to spread during her tenure as President of Madrid. "Please go, you've caused a lot of harm" said Carmena to Aguirre.

In the last days of the campaign, especially following her debate with Aguirre, several celebrities such as actors Pilar Bardem, Carlos Bardem, Loles León, Goya Toledo, Paco León, playwright Cristina Rota, lawyer and former politician Cristina Almeida and journalist Ernesto Ekaizer expressed their support for Carmena's candidacy, with actress Eva Hache going on to say through the Twitter social network that "I don't know if we are Manuela but surely we are not the other [in reference to Aguirre]. VOTE." Carmena had also received the support of dozens of artists who created drawings in support of Carmena's and Ahora Madrid candidacy, with the drawings themselves becoming viral in the social networks. Following the Telemadrid debate, after which Aguirre was highly criticised for her aggressive behaviour towards Carmena, supporters cast the drawings next to Aguirre's home in Malasaña. On 21 May, a Carmena's act in the center of Madrid exceeded its capacity, originally scheduled for 800 people, resulting in the closing of a street and in Carmena herself apologizing to the around 1,500 people outside that were not able to enter.
