2007 Navarrese regional election

The 2007 Navarrese regional election was held on Sunday, 27 May 2007, to elect the 8th Parliament of the Chartered Community of Navarre. All 50 seats in the Parliament were up for election. The election was held simultaneously with regional elections in twelve other autonomous communities and local elections all throughout Spain.

The election saw the ruling coalition formed by the Navarrese People's Union (UPN) and Convergence of Democrats of Navarre (CDN) losing the absolute majority it had enjoyed in the previous legislature, with the newly-formed Navarre Yes (NaBai) alliance—formed by Aralar, Basque Solidarity (EA), the Basque Nationalist Party (PNV) and Assembly (Batzarre)—emerging as the second political force in the region, with the Socialist Party of Navarre (PSN–PSOE) coming in a close third place with its best result since 1991. Negotiations for a coalition government between NaBai, PSN–PSOE and United Left (IUN) ensued, with PSN's candidate Fernando Puras being expected to head the cabinet, but the talks were thwarted by decision from the PSOE's national leadership. As a result, Miguel Sanz was able to be re-elected as president of Navarre for a fourth term thanks to the PSN not opposing his investiture.

Electoral system
The Parliament of Navarre was the devolved, unicameral legislature of the Chartered Community of Navarre, having legislative power in regional matters as defined by the Spanish Constitution and the Reintegration and Enhancement of the Foral Regime of Navarre Law, as well as the ability to vote confidence in or withdraw it from a regional president. Voting was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered in Navarre and in full enjoyment of their political rights.

The 50 members of the Parliament of Navarre were elected using the D'Hondt method and a closed list proportional representation, with a threshold of three percent of valid votes—which included blank ballots—being applied regionally.

Election date
The term of the Parliament of Navarre expired four years after the date of its previous election, with elections to the Parliament being fixed for the fourth Sunday of May every four years. The previous election was held on 25 May 2003, setting the election date for the Parliament on Sunday, 27 May 2007.

The president had the prerogative to dissolve the Parliament of Navarre and call a snap election, provided that no motion of no confidence was in process, no nationwide election was due and some time requirements were met: namely, that dissolution did not occur either during the first legislative session or within the legislature's last year ahead of its scheduled expiry, nor before one year had elapsed since a previous dissolution under this procedure. In the event of an investiture process failing to elect a regional president within a thirty-day period from the first ballot, the Parliament was to be automatically dissolved and a fresh election called. Any snap election held as a result of these circumstances would not alter the period to the next ordinary election, with elected deputies merely serving out what remained of their four-year terms.

Parliamentary composition
The Parliament of Navarre was officially dissolved on 3 April 2007, after the publication of the dissolution decree in the Official Gazette of Navarre. The table below shows the composition of the parliamentary groups in the Parliament at the time of dissolution.

Parties and candidates
The electoral law allowed for parties and federations registered in the interior ministry, coalitions and groupings of electors to present lists of candidates. Parties and federations intending to form a coalition 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 at least one percent of the electorate in Navarre, disallowing electors from signing for more than one list of candidates.

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; 26 seats were required for an absolute majority in the Parliament of Navarre.

Aftermath
Investiture processes to elect the president of the Government of Navarre required for an absolute majority—more than half the votes cast—to be obtained in the first ballot. If unsuccessful, a new ballot would be held 24 hours later requiring only of a simple majority—more affirmative than negative votes—to succeed. If such majorities were not achieved, successive candidate proposals would be processed under the same procedure. In the event of the investiture process failing to elect a regional president within a thirty-day period from the first ballot, the Parliament would be automatically dissolved and a snap election called.
