Turkey at a Crossroads: The Erdogan Government's Campaign Against the CHP and the Erosion of Democratic Politics

Turkey is passing through one of the most serious political tests of the post-2002 era. Over the past eighteen months, President Recep Tayyip Erdogan's government has pursued a systematic legal and administrative campaign against the Republican People's Party (CHP), the country's main opposition force and the party founded by Mustafa Kemal Ataturk. What began as scattered corruption investigations against opposition mayors has escalated into a full assault on the institutional structure of the CHP itself. On 21 May 2026, an Ankara appeals court annulled the party's 2023 congress and effectively removed its elected chairman, Ozgur Ozel, replacing him with his predecessor Kemal Kilicdaroglu. The opposition has called the ruling a "judicial coup". Combined with the imprisonment of Istanbul Mayor Ekrem Imamoglu, the detention of hundreds of CHP officials, and the appointment of the prosecutor who led the crackdown as Justice Minister, these moves point to a clear pattern: the dismantling of organised political competition before the next presidential election.

The CHP Under Siege

The current crisis cannot be understood without returning to March 2024, when the CHP delivered the worst electoral defeat in the history of Erdogan's Justice and Development Party (AKP). The opposition swept the five largest cities in Turkey, including Istanbul, Ankara, Izmir, Bursa, and Antalya. For the first time in more than two decades, Erdogan faced a credible institutional rival with national reach, popular legitimacy, and a clear presidential candidate in Imamoglu.

The government's response did not come through politics. It came through the courts and the prosecutor's office.

The crackdown began in October 2024, when Ahmet Ozer, the CHP mayor of Istanbul's Esenyurt district, was jailed on alleged links to the outlawed Kurdistan Workers' Party (PKK). It expanded in January 2025 with the arrest of Besiktas Mayor Riza Akpolat. By March 2025, the campaign reached its peak with the pre-dawn detention of Imamoglu, only days before the CHP was due to nominate him as its presidential candidate for 2028. Imamoglu has remained in prison since, facing charges ranging from corruption and bribery to terrorism and espionage. Prosecutors have demanded a sentence exceeding 2,000 years against him in a single 4,000-page indictment.

According to a Reuters review, Turkish law enforcement agencies have detained more than 500 people, including 16 mayors, across Istanbul and other CHP-run municipalities. The CHP rejects the charges as politically motivated. The government insists the judiciary acts independently.

The May 2026 Ruling: A Turning Point

The 21 May 2026 decision by the Ankara Regional Court of Justice's 36th Civil Chamber represents a qualitative escalation. By annulling the CHP's 2023 congress on grounds of unspecified "irregularities", the court did not merely target individual opposition figures. It struck at the legitimacy of the party's internal democratic processes.

The reinstated leader, Kemal Kilicdaroglu, is a deeply divisive figure within the CHP. He led the party for thirteen years and lost the 2023 presidential election to Erdogan, a defeat that produced the internal revolt which brought Ozel to power. Returning him to the chairmanship, against the will of the party base, weakens the CHP from within at the precise moment it needs unity. The court has, in effect, decided who leads the opposition.

Ozel has refused to vacate the position, vowing to remain "day and night" at party headquarters in Ankara and pursue every legal appeal available. The party has framed the ruling as a "judicial coup". Yet the structural damage is already done. Whichever way the appeals process moves, the message has been delivered: in Turkey today, the leadership of an opposition party can be removed by a court ruling.

The Architecture of Consolidation

Three developments, taken together, reveal the underlying strategy.

First, the capture of the judiciary. In February 2026, Erdogan appointed Akin Gurlek, the Istanbul chief prosecutor who personally led the cases against Imamoglu and the CHP, as Justice Minister. The man who built the indictments is now the man who supervises the system of justice. The signal to prosecutors and judges across the country could not be clearer.

Second, the fragmentation of judicial hierarchy. As Commerzbank analysts noted in late 2025, lower civil courts have repeatedly issued rulings that override the authority of higher bodies such as the Supreme Election Council. Multiple courts have been used in parallel to produce overlapping pressures on the CHP, including the annulment of provincial congresses and the dismissal of local party administrators. This fragmentation is not chaos; it is a method. It multiplies the points of legal attack while diffusing accountability.

Third, the timing. Erdogan, now 72, has reached his constitutional term limit. The next presidential election is set for 2028, but he cannot run again unless the vote is brought forward or the constitution is amended. The systematic weakening of the CHP, the removal of Imamoglu, and the installation of a divisive figure at the head of the opposition all point toward an environment designed for an early election, held under conditions that maximise the incumbent's advantage.

The Economic Cost

The political crisis has produced immediate economic damage. Following the 21 May ruling, the Borsa Istanbul BIST 100 index fell more than 6 percent, triggering a circuit breaker. Banking shares dropped more than 8 percent. The lira came under renewed pressure, forcing state intervention to defend the currency. JPMorgan revised its forecast upward, anticipating an emergency rate hike by the central bank.

These reactions follow a familiar pattern. The arrest of Imamoglu in March 2025 had already produced the worst single-day lira decline since the 2023 currency crisis, with the central bank reportedly selling between 5 and 10 billion dollars in foreign exchange reserves to stabilise the market.

The economic logic is clear. Turkey's recovery programme, designed by Finance Minister Mehmet Simsek since 2023, depends on foreign capital inflows, tight monetary policy, and credibility. Political shocks of this scale corrode all three. Each move against the opposition imposes a measurable cost on the Turkish economy, paid by ordinary citizens through inflation, currency weakness, and lost investment.

The Democratic Damage

The institutional erosion runs deeper than any single ruling or arrest. Three lasting harms can already be identified.

The first is the collapse of the boundary between law and politics. When the same prosecutor who built cases against the opposition becomes Justice Minister, when courts can annul party congresses and replace elected leaders, the distinction between legal process and political instrument disappears. This damage is not easily repaired, regardless of who governs Turkey in the future.

The second is the chilling effect on political participation. Mayors, council members, party officials, and activists now operate under the credible threat of detention. Hundreds have already been jailed. The cost of opposition politics has been raised to a level that deters new entrants and exhausts existing ones.

The third is the erosion of the electoral promise itself. The CHP's 2024 victories were the largest democratic mandate delivered to an opposition party in a generation. The government's response has been to neutralise those victories through legal means rather than accept them politically. This sends a signal to Turkish voters that elections may produce results, but those results can be reversed by courts, prosecutors, and administrative tools.

International Dimension and the Kurdish Question

The crackdown has unfolded alongside a parallel and largely unrelated development: the disbanding of the PKK in May 2025, following negotiations with its jailed leader Abdullah Ocalan. The end of the four-decade armed conflict is a genuine achievement and could, in another political environment, produce significant democratic openings.

Instead, the timing has created uncomfortable questions. Some analysts suggest that the Kurdish peace track gives Erdogan room to consolidate domestically without facing the security pressures that have historically constrained Turkish governments. Others note that several CHP mayors have been jailed precisely on alleged PKK links, even as the government negotiates with the organisation itself. The contradiction is striking.

International responses have remained measured. Germany has urged Ankara to respect democratic standards. The European Court of Human Rights has issued multiple binding rulings that Turkey continues to ignore. After Erdogan's meeting with US President Donald Trump, the US ambassador to Turkey, Tom Barrack, was quoted as saying that "Trump gave Erdogan legitimacy and as a result, you will see major changes soon". For Western capitals, strategic interests in NATO, migration, and regional security continue to outweigh concerns about Turkish democracy.

A Shrinking Opposition Field

To understand the full weight of the assault on the CHP, it must be placed in its wider political context. The CHP is not one opposition party among several. It is the only opposition force left in Turkey capable of challenging Erdogan on a national scale. Every other potential counterweight has either been absorbed, marginalised, or placed under structural constraints that limit its independence.

The pro-Kurdish Peoples' Equality and Democracy Party (DEM), the third largest force in parliament, illustrates this dynamic with particular clarity. DEM holds genuine electoral weight in the southeast and a decisive bloc in the National Assembly. In any normal political environment, it would be a natural partner for the CHP in resisting the government. Instead, DEM has been effectively neutralised through its entanglement in the Kurdish peace process.

The mechanism is elegant in its design. Since Abdullah Ocalan's February 2025 call for the PKK to disarm, and the group's formal decision in May 2025 to disband, DEM has played the central role as intermediary between Ankara and the Imrali island prison where Ocalan is held. The party's leadership, including co-chairs and authorised delegations, has met repeatedly with Erdogan to keep the process moving. The PKK has begun handing over weapons. A parliamentary commission has been established to address legal and constitutional reforms tied to disarmament.

This places DEM in a position of acute political dependence. The peace process represents a historic opportunity for Kurdish political and cultural rights, including the prospect of constitutional recognition, the reintegration of fighters, and the release of political prisoners. None of these gains can be secured without the government's cooperation. DEM cannot openly join a broad opposition front against Erdogan without putting the entire process at risk.

The government has used this leverage deliberately. While negotiating with DEM at the presidential complex, the same government has jailed CHP mayors on alleged PKK links, including the Esenyurt mayor Ahmet Ozer whose detention in October 2024 opened the current crackdown. The contradiction is not a contradiction at all. It is a strategy. The Kurdish peace track buys DEM's restraint, while terrorism charges built on the same Kurdish question are used to dismantle the CHP. One opposition party is held by hope, the other by handcuffs.

DEM itself has shown growing frustration. The party's co-chair Tulay Hatimogullari publicly accused the government in April 2026 of acting in a "hesitant, timid and stalling manner". DEM leaders have warned Erdogan against treating the rolling back of Kurdish gains in Syria as a reason to abandon the process in Turkey. But these criticisms are constrained by the same dependence that produced them. Walking away from the peace track means losing everything the party has invested in it.

The smaller nationalist and centrist parties offer no alternative. The IYI Party, once a significant component of the opposition alliance, has lost relevance since the 2023 election. The far-right MHP remains Erdogan's coalition partner and has actively driven the Kurdish peace process from the government side. The Islamist parties operate in Erdogan's ideological space. There is no political formation outside the CHP with the national reach, the institutional infrastructure, and the urban support base required to mount a presidential challenge.

This is the deeper meaning of the campaign against the CHP. The government is not weakening one opposition party. It is removing the last remaining opposition party that can plausibly defeat Erdogan at the ballot box. The DEM Party, however significant in parliament, is structurally unable to play that role under current conditions. Once the CHP is fragmented through judicial intervention and internal division, the field is effectively cleared.

What Comes Next

Three scenarios deserve close attention.

The first is institutional resistance. The CHP retains significant popular support, control of major municipalities, and a leadership willing to fight. If Ozel can sustain his appeal and mobilise public protest, the ruling may yet be reversed or rendered ineffective. The October 2025 dismissal of a similar case against him shows that the judicial machinery is not fully closed.

The second is fragmentation. The reinstatement of Kilicdaroglu may produce open conflict within the CHP between his loyalists and Ozel's base. This is plausibly the intended outcome. A divided opposition cannot mount a credible challenge in 2028 or in any earlier vote.

The third, and most consequential, is an early election. With the opposition's leadership in dispute, its presidential candidate in prison, and its institutional structure under legal attack, the government may judge that conditions are favourable to bring forward the vote. Erdogan needs a constitutional path to run again. The political ground is being prepared.

Conclusion

Turkey is not a country sliding gradually toward authoritarianism. It has been moving in that direction for years. What is distinctive about the present moment is the open use of the judicial system to determine who can lead the opposition, who can run for office, and who can hold elected positions won at the ballot box. The CHP's crisis is not the CHP's alone. It is the crisis of competitive politics in Turkey, taking place at a moment when no other opposition force is positioned to fill the vacuum. The DEM Party is bound by the peace process. The smaller parties lack national weight. If the CHP is fragmented, the political field is cleared.

The next eighteen months will determine whether the country still possesses the institutional resilience to hold a meaningful presidential election, or whether 2028, or an earlier vote, will be conducted in a political landscape engineered by prosecutors and courts rather than chosen by voters. The economic costs are already visible. The democratic costs will take longer to measure, but they will be far greater.
