Around a thousand demonstrators from Spain’s left-wing parties took to the streets of Madrid on Saturday to protest the government’s plans to increase military spending, a move they say betrays the country’s progressive values and risks undermining social programs.
The protest, organized by parties including Podemos, Izquierda Unida (IU), and Sumar, came as Prime Minister Pedro Sánchez’s government moves to align with NATO demands for higher defense budgets — a policy shift backed by European allies and encouraged by former U.S. President Donald Trump.
The demonstration took on added political weight following recent remarks from IU’s parliamentary spokesman Enrique Santiago, who warned that the party’s continued presence in the governing coalition is in jeopardy. Santiago stated it would be “practically impossible” for IU to remain in a government that embraces such a militarized course, urging Sánchez to resist NATO pressure ahead of the upcoming summit in The Hague later this month.
“We categorically reject the increase in defense spending,” Santiago said, referring to the expected NATO push for member countries to raise their military budgets to as much as 5% of GDP — more than double the current target.
Among the most notable presences at the protest was that of Sumar, the broad leftist coalition led by Labour Minister Yolanda Díaz. Though Díaz has yet to formally break with the government, her continued opposition to the defense spending plan underscores growing fractures within the ruling alliance as it prepares for the NATO summit.
Podemos, another coalition member, issued some of the strongest criticism on Saturday. Prominent MEP Irene Montero denounced the defense budget hike as a “betrayal” of Spain’s progressive principles and warned that increased military funding could pave the way for future cuts in social welfare programs. Montero specifically cited threats to public education and initiatives like the Co-Responsibles Plan, which supports family work-life balance.
The protest highlighted a deepening ideological divide within Spain’s left, with demonstrators carrying signs and chanting against rearmament and what they view as capitulation to NATO’s strategic agenda.
As tensions mount within the governing coalition, the debate over defense spending is likely to remain at the forefront of Spanish politics — especially with international pressure growing ahead of key decisions on military budgets later this month.
