The UPN won only 15 seats, down four from 2011, while their allies the right-wing Spanish People’s Party (of Spanish Prime Minister Mariano Rajoy) won 2, half of their quota in 2011.
Instead, Uzue Barkos, leader of the pro-Basque coalition Geroa Bai (“Yes to the Future”) – itself a coalition of centre-left Basque nationalist association Zabaltzen and the centre-right Basque Nationalist Party (EAJ-PNV) – approached other pro-Basque parties to negotiate a coalition government after her party won 9 seats.
In order to form government, Geroa Bai needed to secure 26 seats in the 50-seat Navarrese parliament – 17 more than their direct mandate.
Geroa Bai immediately entered into discussions with the Basque leftist pro-independence coalition Euskal Herria Bildu ("Basque Country Unite", EH Bildu), which won 8 seats, the new Spanish anti-austerity party Podemos (7 seats) and the left-federalist Izquierda-Ezkerra ("Left-Left", I-E) – the Navarra affiliate of Spain's Izquierda Unida ("United Left") – with 2 seats.
