President before election

José Montilla

Elected President

Artur Mas

The 2010 Catalan regional election was held on Sunday, 28 November 2010, to elect the 9th Parliament of the Autonomous Community of Catalonia. All 135 seats in the Parliament were up for election.

The election resulted in the ousting of the Catalan tripartite coalition, composed of the Socialists' Party of Catalonia (PSC), Republican Left of Catalonia (ERC) and Initiative for Catalonia Greens (ICV) from the Catalan government and the return to power of Convergence and Union (CiU) after 7 years in opposition.

Artur Mas was sworn in as President of the Generalitat of Catalonia and was able to govern with confidence and supply support from the People's Party of Catalonia (PPC) until Mas' independentist drift in late-2012.

Electoral system[edit]

No electoral law was in force at the time, with election rules for the Parliament regulated under the electoral system for the Congress of Deputies and special provisions within the regional Statute of Autonomy. The Parliament of Catalonia was elected using the D'Hondt method and a closed list proportional representation. Under the Statute, the Parliament was entitled to a minimum of 100 members and a maximum of 150, which provisional statutory rules set to 135. All seats were allocated to four multi-member districts—each corresponding to a province, with allocation awarding 85 seats to Barcelona, 17 to Girona, 15 to Lleida and 18 to Tarragona—. A threshold of 3% of valid votes—which included blank ballots—was applied in each constituency, with parties not reaching the threshold not taken into consideration for seat distribution.

Voting was on the basis of universal suffrage, with all residents over eighteen and in the full enjoyment of all political rights entitled to vote. Concurrently, residents meeting the previous criteria and not involved in any cause of ineligibility were eligible for the Parliament. Gender quotas were introduced in 2007, requiring for party lists to be composed of at least 40% of candidates of either gender and for each group of five candidates to contain at least two males and two females. Groups of electors were required to obtain the signatures of at least 1% of registered electors in a particular district in order to be able to field candidates.

The President had the ability to dissolve the chamber at any given time and call a snap election; otherwise, elected deputies served for four year terms, starting from election day. Additionally, the Parliament was to be automatically dissolved in the event of unsuccessful investiture attempts failing to elect a President within a two month-period from the first ballot, triggering a snap election likewise.[1][2][3]

Opinion polls[edit]


Poll results are listed in the table below in reverse chronological order, showing the most recent first, and using the date the survey's fieldwork was done, as opposed to the date of publication. If such date is unknown, the date of publication is given instead. The highest percentage figure in each polling survey is displayed in bold, and the background shaded in the leading party's colour. In the instance that there is a tie, then no figure is shaded. The lead column on the right shows the percentage-point difference between the two parties with the highest figures. When a specific poll does not show a data figure for a party, the party's cell corresponding to that poll is shown empty.

Seat projections[edit]

Opinion polls showing seat projections are displayed in the table below. The highest seat figures in each polling survey have their background shaded in the leading party's colour. In the instance that there is a tie, then no figure is shaded. 68 seats were required for an absolute majority in the Parliament of Catalonia.

Voting preferences[edit]

Vote intention[edit]

Polls shown below show the recording of raw responses for each party as a percentage of total responses before disregarding those who opted to abstain and prior to the adjusting for the likely votes of those who were undecided to obtain an estimate of vote share. The highest percentage figure in each polling survey is displayed in bold, and the background shaded in the leading party's colour. In the instance that there is a tie, then no figure is shaded.
