A court ruling that removed Turkey’s main opposition leader has opened a new phase of political instability, raising questions over the future of the CHP, early elections and Ankara’s reliability as a European and NATO partner.
Turkey’s main opposition party has been pushed into a fresh leadership crisis after its ousted chairman called for a new party congress within about 40 days, following a court ruling that annulled the 2023 vote which had brought him to power.
The dispute centres on the Republican People’s Party, or CHP, Turkey’s main opposition force and the party that won a major victory in the 2024 local elections. A Turkish appeals court this week annulled the CHP’s 2023 congress, removed Özgür Özel as party leader and reinstated his predecessor, Kemal Kılıçdaroğlu. The ruling has been challenged by Özel, who described it as a judicial intervention in party politics.
The crisis deepened on Saturday when Turkish police detained 13 people across seven provinces as part of an investigation into alleged vote manipulation at the 2023 congress. The allegations include bribery and money laundering, according to state media cited in reporting on the investigation.
The case now places Turkey’s opposition under pressure at three levels: legal, organisational and electoral. The CHP must decide whether it can restore internal authority through a new congress, whether Özel can remain the opposition’s effective political figurehead, and whether the court ruling will weaken the party before any possible early national election.
Özel has said he will continue to lead the CHP’s parliamentary group, and Reuters reported that 110 of the party’s 138 lawmakers supported him. Kılıçdaroğlu, meanwhile, has called for party members to avoid language that could divide the CHP’s grassroots. His return to the formal leadership, even temporarily, risks reopening internal divisions that the party appeared to have moved beyond after its 2023 congress.
The timing is politically significant. The CHP’s 2024 local election success was widely viewed as a setback for President Recep Tayyip Erdoğan’s ruling AK Party. The opposition’s strength in major cities, particularly Istanbul and Ankara, gave it a stronger national platform and placed renewed attention on whether Erdoğan could face a more competitive challenge before the next presidential contest.
The court ruling has therefore been interpreted by critics as more than an internal party matter. It follows a broader pattern of investigations, detentions and legal proceedings involving opposition figures. The Turkish government has said the judiciary operates independently, but the cumulative effect of the cases has intensified concern among opposition parties and foreign observers over political competition in Turkey.
There is also a market dimension. The earlier ruling removing Özel contributed to financial pressure, with Turkey’s main stock index falling sharply and the central bank intervening in foreign exchange markets to support the lira, according to financial reporting on the court decision. Political uncertainty in Turkey often carries economic consequences because investors are sensitive to judicial independence, central bank credibility and the prospect of abrupt policy shifts.
For Europe, the issue is not only domestic Turkish politics. Turkey remains a NATO member, a Black Sea power, a central actor in migration management, and a difficult but necessary partner for the European Union. Instability in Turkey’s opposition does not change those facts, but it does affect the political environment in which European governments must manage relations with Ankara.
The EU has long had a strained relationship with Turkey over democracy, rule of law, migration, customs union modernisation, energy, Cyprus and regional security. The latest CHP crisis adds another complication. European governments may avoid direct intervention in an internal party dispute, but the question of whether Turkey’s opposition can compete freely is relevant to the broader assessment of Ankara’s political direction.
The NATO context is equally important. Turkey’s strategic position gives it influence over alliance decisions, Black Sea security, relations with Russia and defence cooperation. A more polarised domestic political environment could make Ankara’s foreign policy harder to read, particularly if the government presents external disputes as part of domestic political messaging.
The legal process surrounding the CHP also matters because of timing. Erdoğan is constitutionally due to leave office in 2028 unless political conditions create a route to another presidential bid or an earlier election changes the timetable. Speculation over an early election has increased as the opposition dispute unfolds, although no such vote has been formally called.
The immediate question is whether a new CHP congress can settle the leadership issue or whether it will deepen the split. If Özel secures renewed support, the party may present the process as a response to judicial pressure. If the congress becomes contested, the opposition could lose organisational focus at a critical moment.
For the EU and NATO, the outcome will be watched less as a party procedural dispute than as a test of Turkey’s political stability. A weakened or divided opposition would alter the country’s electoral balance. A stronger opposition response could increase pressure on Erdoğan. Either way, the court ruling has turned an internal CHP congress into a wider measure of Turkey’s democratic and strategic direction.
