The Broad Front is made up of Sumar, the current junior partner in the Socialist-led government, the Catalan Comuns, the Communist-led United Left and Más Madrid. Some smaller local parties have also joined the ticket. The lead candidate for prime minister will be Ada Colau, the former mayor of Barcelona.
Sumar, the dominant force in the alliance, has seen its vote share more than halve since 2023, to 5%, according to POLITICO’s Poll of Polls.
Although Podemos has only been polling at 3%, its full involvement in the Broad Front would have meant a greater overall share of seats for the far left, according to analysts.
The PSOE has been trailing the conservative People’s Party and would need a strong performance by parties to its left in order to keep Sánchez in office. The more likely scenario, polls show, is that the PP will be able to form a majority with the far-right Vox, whose support has been rising.
“The Spanish left is caught up in a game of thrones that demobilizes [voters],” said Irene de Miguel, coordinator of Podemos in the western region of Extremadura, as the deadline loomed.
