Political transitions are occurring in Soria ahead of the upcoming Senate elections. Yolanda de Gregorio and Benito Serrano have announced their departures from institutional roles to run as candidates for the Partido Popular. De Gregorio will step down from her position as delegate for the Junta de Castilla y León, with Rafa Medina expected to serve in an interim capacity.

In response to these shifts, the PSOE and Frente Amplio have formed a coalition named ‘Senado de Progreso’ to run jointly in Soria. This agreement modifies the socialist candidate list to include Frente Amplio, represented by Izquierda Unida, in the second position. The candidacy is led by Ana Alegre Martínez of the PSOE and Manuel Madrid Castro of Izquierda Unida.
