Both Cs and PP leader Pablo Casado—who described his party's dismal performance as "very bad" but rejected to resign from his post—vyed for the leadership of the opposition to Sánchez's government, with far-right Vox having entered parliament for the first time. As a result of the election, the Spanish right was fragmented into three slices which, even taking regional allies such as Navarrese People's Union (UPN) into account, could only muster 149 seats, far from any prospective shot at forming a government. Rivera quickly rejected any chance of agreement with the PSOE, pointing out that "Sánchez and Iglesias are going to govern with the nationalists", despite attempts from both PSOE and PP to court the party into abstaining in order to allow the investiture process to proceed.
