Izquierda Unida, Más Madrid, Comuns and Movimiento Sumar will present the Frente Amplio on October 17. They still need to settle its leadership and Podemos' role before a possible early election closes the gap for negotiations.
On October 2, Congress rejected the Government's two housing decrees. The first vote failed by 178 to 172. The second ended 184 to 166, according to Reuters, AP, BBC and DW. PP, Vox and Junts supplied the votes that brought them down.
The defeat came as housing pressure was already spilling into the streets. Hundreds of thousands of people demonstrated in several cities the next day. They demanded solutions to a crisis that now affects several generations.
The rejected package went beyond direct housing assistance: it included a ban on evictions of vulnerable tenants until 2030, an extension of the rent freeze, tighter rules for short-term rentals and automatic or indefinite lease renewals.
Housing now gives the new alliance its clearest political argument. The issue must stay at the centre of the next electoral cycle.
The defeat also exposed the price of eight months of hesitation. Yolanda Díaz gave up the candidacy and left the space without an agreed structure or leader.
The October 17 presentation may come too late for a full deal. If Pedro Sánchez calls an election for November 29, the legal deadline for registering coalitions would fall on October 16, one day before the Frente Amplio event. The four parties would then have only hours to finish talks that have stalled for most of the year.
The leadership question remains open.
Junts had signalled before the vote that it would not support the decrees and had demanded a new version of the text. After Congress rejected them, the repeal of both royal decrees was published in Spain’s Official State Gazette, confirming the legal effect of the parliamentary defeat.
Mónica García is one of the strongest options among groups on the alternative left. Under the proposal, the Sanidad minister would lead the Madrid list. Ernest Urtasun would head the Barcelona candidacy.
Ada Colau also has support inside the alliance. Pablo Bustinduy has ruled himself out. He had led the space's parliamentary and negotiating work on housing. None of these names has been confirmed. The leadership remains part of an internal negotiation.
Podemos is the hardest piece to fit into the plan. Its leaders want open primaries and are backing Irene Montero for the top position. Más Madrid rejects that method. Izquierda Unida is willing to consider it. The parties still have no agreement on the voting system, and an early election would make the process exceptionally difficult.
The housing dispute has exposed the left's central problem. The issue connects the new alliance with public anger. The parliamentary defeat has also made internal division more costly.
Earlier housing coverage showed how the same vote can become a policy dispute and an electoral weapon for opposing parties. The BBC reported that the defeat also increased pressure on Sánchez to call an early election.
A wider meeting is scheduled for Monday. Compromís, Chunta Aragonesista and Més have been invited alongside Sumar's five ministers. The group wants to widen the alliance, sort out the competing demands and agree on a common position before October 17.
Sumar sped up the effort after the housing defeat and the protests. The October 17 presentation is now the next public test.
The Frente Amplio is being built against a deadline. Its launch will show whether the parties have turned the housing defeat and the street protests into a working electoral project. It may instead expose the same leadership dispute under a new name.
The facts point to one immediate test. The alliance must include Podemos and resolve the primaries question before the calendar closes in.
