Overview
Navarra Suma (, NA+) was an electoral alliance in Navarre formed by Navarrese People's Union (UPN), Citizens (Cs) and the People's Party (PP) ahead of the April 2019 Spanish general election and kept for the May 2019 local and regional elections. The goal of the three parties was to create a broad coalition of anti-nationalist centre-right forces in Navarre.
NA+ was noted for its success in consolidating the vote of the centre-right to right-wing in Navarre as well as mitigating the rise of Vox, but at the cost of hindering chances for any agreement between UPN and the Socialist Party of Navarre (PSN) that would have allowed it to return to government.
History
The alliance had its precedent in the 2015 Navarrese regional and Spanish local elections, where the Navarrese People's Union (UPN), the People's Party (PP) and Citizens (Cs) had run separately, leading to significant vote splitting within the centre-left to right-wing political spectrum that favoured the election of left-wing governments both at the regional and the local level, including the loss of Pamplona to an EH Bildu's controlled council. This circumstance was seemingly about to be repeated in the upcoming 2019 regional, local and, eventually, April general elections, with the aggravating circumstance of a fourth party gaining strength within the far-right side of the spectrum: Vox.
After several months of speculation on whether UPN and PP would renew their traditional general election alliance, an agreement was reached on 2 March 2019 whereby the PP would fully respect UPN's condition of seeking to "maintain an autonomous voice in Madrid". Throughout the next week, it was unveiled that UPN had entered talks with Cs to form a three-way alliance comprising all three elections—general, regional and local—with the decision being approved by the parties on 10 March and officially signed by UPN and Cs leaders, Javier Esparza and Albert Rivera, on the next day. The overall agreement was formally presented as an alliance between UPN and Cs, with the former integrating some PP members within its reserved posts in the coalition's lists, by virtue of the previous agreement between the two parties. UPN explicitly excluded Vox from the alliance on the basis that its purpose was to avoid vote splitting between three similarly-aligned parties, hinting that Vox's political strategies were distinct enough to their own.
