Party Analysis: SYRIZA (Greece)

The Afterlife of Anti-Austerity Politics

SYRIZA was once the most powerful challenge to Europe’s post-crisis economic order; today it is a diminished and divided force struggling to define its purpose. Founded in 2004 as the Coalition of the Radical Left, SYRIZA brought together communists, social democrats, ecologists, and activists under a shared rejection of neoliberal orthodoxy. It rose from the margins to government during Greece’s sovereign debt crisis, briefly transforming national politics and reshaping debates far beyond Athens.

Yet by late 2025, SYRIZA’s position is starkly reduced. Led by Sokratis Famellos since November 2024, the party holds just 26 seats in the 300-member Hellenic Parliament, down from 47 elected in June 2023 and far below its 2015 peak. Opinion polls place its support between 3.6 and 7.2 per cent, averaging barely above the parliamentary threshold. Once the dominant force on the Greek left, SYRIZA now competes with splinter parties for relevance, its authority eroded by leadership turmoil, defections, and the fading salience of the crisis politics that once sustained it.

Why SYRIZA Exists

SYRIZA emerged from the long collapse of Greece’s post-authoritarian centre-left. By the late 2000s, PASOK - historically the principal vehicle of social democracy - had lost credibility after accepting EU-mandated fiscal consolidation and structural reforms. As the debt crisis intensified between 2008 and 2012, wage cuts, pension reductions, and mass unemployment created fertile ground for a party willing to challenge the prevailing consensus.

SYRIZA filled that vacuum. It offered an explicitly anti-austerity platform centred on debt relief, public ownership, labour protections, and democratic resistance to what it framed as externally imposed neoliberalism. Under Alexis Tsipras, the party channelled protest movements into electoral mobilisation, transforming a loose coalition of factions into a national governing contender.

But the conditions that enabled SYRIZA’s rise also sowed the seeds of its later fragmentation. The compromises required by government - particularly the acceptance of bailout terms after the 2015 referendum - split the party between pragmatists and purists. Over time, ideological coherence gave way to internal distrust. The emergence of breakaway formations, including the New Left in 2023 and Stefanos Kasselakis’s Movement for Democracy in 2024, reflected not just personal rivalries but unresolved tensions over what SYRIZA was for once resistance proved insufficient.

What the Party Has Achieved

SYRIZA’s achievements are inseparable from the crisis decade that propelled it. In 2012, it surged to 26.9 per cent of the vote and became the main opposition. Two years later, it topped the European Parliament elections and secured control of the Attica regional government. Its twin election victories in January and September 2015 - each delivering around 35 - 36 per cent of the vote - brought it to power at the height of Greece’s confrontation with its creditors.

In government, SYRIZA both constrained and expanded policy space. While it ultimately accepted bailout conditions, it also raised the minimum wage, expanded access to healthcare, and passed progressive social legislation, including same-sex civil unions and gender identity recognition. Capital controls were lifted and fiscal stability restored, but at the cost of internal unity and ideological clarity.

Since losing office in 2019, SYRIZA has struggled to recalibrate. Electoral defeats in 2019 and 2023 reduced its parliamentary presence, while leadership changes - from Tsipras’s resignation to Kasselakis’s brief and controversial tenure, followed by Famellos’s appointment - have reinforced perceptions of drift. Although the party continues to shape debate on inequality and austerity’s legacy, its recent interventions, such as symbolic campaigns over cultural issues, have underscored the gap between its ambitions and its dwindling leverage.

What Success Would Look Like

For SYRIZA, success can no longer mean a simple return to the politics of 2015. The conditions that enabled its original breakthrough - economic collapse, mass protest, and delegitimised elites - no longer obtain. Instead, success would involve rebuilding credibility as a coherent centre-left alternative capable of surviving electoral competition and institutional constraints.

In the short term, this means clearing the 3 per cent threshold comfortably and re-establishing itself as the primary representative of the radical and progressive left. Medium-term success would involve consolidating alliances - whether through reunification with splinter groups or cooperation with PASOK - to prevent further vote fragmentation. Over the longer term, SYRIZA would need to articulate a post-austerity project that speaks to stagnant wages, housing insecurity, and public service decline without relying on crisis rhetoric that has lost its mobilising power.

Absent such renewal, the party risks becoming a residual force: symbolically important, but electorally marginal.

Electoral Rules and Strategic Constraints

Greece’s reinforced proportional representation system has magnified SYRIZA’s difficulties. The 3 per cent national threshold and the majority bonus awarded to the largest party favour consolidated blocs and punish fragmentation. In 2023, this system allowed New Democracy to convert a clear plurality into an outright majority, marginalising divided opponents.

For SYRIZA, fragmented support is particularly damaging. While urban constituencies offer potential gains, vote splitting on the left pushes the party below thresholds in smaller districts. Polling around 5 per cent places it in a precarious position, where minor losses could mean parliamentary exclusion altogether.

Coalition politics could, in theory, restore relevance in a hung parliament. In practice, internal instability, leadership uncertainty, and speculation about a possible new Tsipras-led formation threaten further erosion. Without organisational renewal and grassroots rebuilding, electoral mechanics will continue to work against it.

How Critics See It

SYRIZA’s critics are unusually diverse. On the centre-right, New Democracy portrays the party as fiscally reckless and institutionally irresponsible, blaming its 2015 brinkmanship for prolonged economic uncertainty. On the far right, SYRIZA’s progressive positions on migration and social policy are framed as naïve or dangerous.

From within the broader left, PASOK and other rivals accuse SYRIZA of hypocrisy - denouncing austerity while ultimately administering it - and of internal authoritarianism masked by radical rhetoric. Symbolic gestures, such as cultural boycotts, are dismissed as performative distractions from bread-and-butter issues. Across the spectrum, SYRIZA is increasingly depicted not as a credible alternative government, but as a party trapped by its own past.

How It May Be Remembered

SYRIZA’s historical legacy is likely to outstrip its current strength. Even if it never returns to power, it will be remembered as the political expression of Greece’s anti-austerity revolt - a moment when democratic resistance to technocratic governance briefly reshaped European politics.

If the party manages to regroup, forge alliances, and adapt to post-crisis realities, it may yet be credited with moderating EU fiscal orthodoxy and embedding progressive social reforms. If not, it will stand as a cautionary tale: a movement forged in crisis that faltered once protest gave way to governance, undone by compromise, fragmentation, and the exhaustion of the moment that made it possible.

Either way, SYRIZA changed Greek politics - and Europe noticed.
