Spain’s parties to the left of the socialists (PSOE) will contest most of the country separately in the 29 November general election after negotiations between the Frente Amplio (‘Broad Front’ in English) and Podemos failed to produce a nationwide agreement.
The breakdown leaves two rival candidacies competing for much of the same electorate, potentially weakening Prime Minister Pedro Sánchez’s chances of securing another term. Beyond the risk of losing seats through a divided vote, the public disputes have raised concerns about whether disappointed supporters will turn out.
The deadline for registering coalitions passed on Friday with agreements between the two sides limited to the Valencia region and the Canary Islands. Elsewhere, Frente Amplio and Podemos will largely pursue separate campaigns.
Former Barcelona mayor Ada Colau (left, main image), Frente Amplio’s candidate for prime minister, and former equality minister Irene Montero (right), standing for Podemos, launched their respective campaigns on Saturday while offering sharply different explanations for the failure.
Rival launches and mutual recriminations
Speaking at the Frente Amplio’s presentation in Madrid’s Parque Lineal del Manzanares, Colau acknowledged the frustration of voters who had hoped for a broader alliance.
‘There will be people who are disappointed, and I am sorry, but until the very last minute we did not give up and everything was offered, generously; we extended a hand, but if someone does not want to sit at a table, you cannot force them,’ she said.
Frente Amplio brings together 15 organisations, including Izquierda Unida (IU), Más Madrid, the Catalan Comuns and Sumar (now referred to as ‘Moviemiento Sumar’). Colau heads its Barcelona list, with Spain’s current Culture Minister Ernest Urtasun in second place, while Más Madrid politician Emilio Delgado leads its candidacy in Madrid.

Colau urged supporters to concentrate on the campaign and confronting the far right. She also sought to distinguish the alliance from Sánchez’s PSOE socialist party, arguing that the left needed to be ‘much braver’ in government rather than relying on warnings about Vox.
At a separate meeting of Podemos’s national leadership, Montero said the limited agreements achieved were ‘valuable’, while accepting that they fell short of many supporters’ expectations.
She accused Frente Amplio parties of prioritising an agreement with the PSOE on joint Senate lists over negotiations with Podemos in regions where, she said, talks had been ‘very advanced or even concluded’.
Montero also rejected the suggestion that the dispute was principally about candidates’ positions, pointing instead to ‘serious political disagreements’ built up over several years.
‘We are very critical of their way of governing and also of their closeness to the PSOE,’ she said.
Why the negotiations failed
The immediate disagreement concerned whether the parties should negotiate a comprehensive national alliance or make separate arrangements constituency by constituency.
Frente Amplio wanted an overall settlement. Podemos favoured agreements in places where running separately would be particularly damaging, while retaining its own candidacies in Madrid and Barcelona, where the larger number of available seats makes it easier for smaller parties to win representation.
Candidate selection was another obstacle. Podemos proposed open primaries to determine places on joint lists. Frente Amplio argued that there was insufficient time and sought to retain its preferred lead candidates in the two largest constituencies.
According to El País, a final written offer made a little over two hours before the deadline included potentially electable positions for Podemos in Madrid and Barcelona, alongside a parliamentary spokesperson role. Earlier, Delgado had said Montero had been offered second place on the Madrid list.
Colau had also indicated a willingness to reconsider her own leadership and the coalition’s name to facilitate an agreement. None of those concessions resolved the wider dispute. ALSO READ: Opinion: three women in Spanish politics – No.1 Ada Colau: agent of change.
Podemos’s own primary subsequently confirmed Montero as its candidate, with 90% support among 26,590 participants. She was the only contender.
Behind the procedural arguments lies a longer struggle over leadership, political identity and relations with the Socialists. ALSO READ: Podemos and 14 other left-wing groups will run in election with Díaz’s Sumar.
Podemos contested the 2023 general election within the Sumar coalition but left its parliamentary group later that year, following bitter disagreements over its influence and exclusion from the new cabinet. ALSO READ: Sánchez excludes Podemos MPs from new cabinet, that has more women than men.
Analysts interviewed by El País argued that the latest negotiations exposed competing priorities: increasing the left’s combined parliamentary representation or preserving individual party identities. Some interpreted Podemos’s approach as an attempt to rebuild its own political standing, an assessment at odds with Montero’s insistence that substantive policy differences prevented agreement.
Rufián’s role divides opinion
A separate arrangement between Podemos and the pro-independence Catalan party, Esquerra Republicana (ERC), further complicated the talks.
Under that agreement, two Podemos members will join ERC’s lists in Catalonia. ERC’s parliamentary spokesperson, Gabriel Rufián, will also take part in a campaign event with Montero in Madrid. ALSO READ: Podemos backs ERC in Catalonia as Spain’s left struggles to agree election alliance.
Rufián had spent months advocating cooperation across the left, encouraging hopes among some supporters that he might lead a wider electoral alliance. He has since insisted that he never intended to leave ERC or head a nationwide Spanish left-wing candidacy.
Hours before Friday’s deadline, he acknowledged that his efforts had fallen short.
‘I apologise to people. I thought that with my influence I could bring the party machinery along, and I probably won’t be able to. I have failed,’ he told Catalan radio RAC1.
Rufián blamed a ‘war of egos’ and defended the Podemos agreement as a practical example of cooperation. Frente Amplio figures, however, argued that it undermined the wider negotiations by aligning Podemos with a direct electoral rival of the Comuns in Catalonia.
Colau accused the partial deal of helping to divide the left, while Comuns MP Aina Vidal described ERC’s approach as an attempted ‘hostile takeover’.
The dispute also illustrates the limits of the original unity project. Catalan, Basque and Galician nationalist parties have their own electorates and political objectives; cooperation with Spain-wide left-wing parties does not necessarily mean joining the same electoral platform.
The electoral cost of division
The consequences could extend beyond the constituencies where rival left-wing candidates compete directly.
Spain elects Congress through provincial constituencies, with smaller provinces returning relatively few MPs. In those areas, votes divided between competing parties can leave both without representation, even when their combined support might have secured a seat.
An early-October 40dB poll cited by El País illustrated the potential difference. It put Sumar on 5.3% and Podemos on 2.3% when standing separately, with projected totals of five and two seats respectively. A joint candidacy was estimated at 9.5% and 15 seats. Those figures describe the scenarios tested in that survey rather than a guaranteed election outcome.
Polling specialists also warned that electoral arithmetic captures only part of the problem. Public arguments can discourage supporters, weaken enthusiasm and encourage voters to choose the PSOE as the most effective way to prevent a right-wing government.

Belén Barreiro, director of 40dB, told El País that unity needed to be credible to mobilise voters. She argued that even an effective alliance would not, on the polling picture she described, necessarily prevent a change of government, although it could improve the left’s seat total.
Repeated changes of party names and coalition partners present a further difficulty: voters must identify which of several overlapping organisations now represents the political option they previously supported.
There was, nevertheless, a significant agreement elsewhere. The PSOE and the Frente Amplio reached a pact for joint Senate lists in 43 provinces, providing a separate avenue for cooperation despite the failure to reach a nationwide Congress deal with Podemos.
Sánchez could benefit individually if disillusioned left-wing voters move towards the PSOE. But his prospects of remaining prime minister also depend on the parliamentary strength of potential partners.
For Colau and Montero, the immediate challenge is therefore to persuade voters that the parties still offer a credible route to political change after weeks dominated by their inability to agree among themselves.
