Turkey’s Jailed Mayor Ditches His Old Party While Erdogan Watches the Opposition Eat Itself

Jailed Istanbul Mayor Ekrem Imamoglu announced on Wednesday that he is joining the newly formed New Party, after a Turkish court order stripped his former Republican People’s Party (CHP) ally Ozgur Ozel of the party leadership and reinstated CHP’s divisive former chairman, Kemal Kilicdaroglu. Ozel and 90 other lawmakers had broken away the previous month to register the New Party with Turkey’s Interior Ministry after Kilicdaroglu refused repeated demands to call a fresh leadership vote [1, 2].

The realignment leaves CHP reduced to 44 seats in the 600-seat parliament, while the New Party — now poised to become the main opposition force — holds 91, against President Recep Tayyip Erdogan’s ruling AKP, which controls 277 [3]. Imamoglu, Erdogan’s leading political rival, has been jailed for more than a year on corruption charges he denies, and was elected CHP’s presidential candidate in an internal party vote days after his March 2025 detention [1, 4]. Erdogan’s government has rejected claims of judicial interference, describing the case as an internal CHP dispute and calling the court’s annulment proof that Turkey’s legal institutions are functioning independently [3].

Why It Sucks:

Erdogan and the AKP Government

• The opposition is doing Erdogan’s job for him. A split that fractures the largest opposition bloc into competing factions removes the need for the AKP to expend political capital attacking a unified rival [1, 3].
• Courts get blamed no matter the outcome. The government insists the CHP leadership case was an internal legal matter handled independently, yet every ruling that damages the opposition gets cast internationally as evidence of a rigged judiciary, undermining Turkey’s institutional credibility regardless of the facts [3].
• A fragmented opposition is a less predictable one. While disarray benefits the AKP short-term, a splintered opposition landscape also makes coalition-building and governance less stable heading into future elections [1, 3].

Imamoglu and the New Party Camp

• Erdogan’s chief rival is running his campaign from a cell. Imamoglu has been imprisoned for over a year facing charges that could carry decades in prison, all while remaining the figure the opposition sees as its strongest challenger to Erdogan [1, 4].
• Their own party leadership pushed them out first. Ozel and 90 lawmakers only broke away after Kilicdaroglu repeatedly refused to hold a new leadership congress, forcing loyalists to build a new party from scratch rather than reform the one they had [2, 3].
• Starting over costs precious time and unity. Rebuilding institutional infrastructure, funding and voter recognition under a brand-new party banner is a steep cost to pay just to escape internal party dysfunction [2, 3].

Kilicdaroglu and the Remaining CHP Loyalists

• A court handed back a leadership voters had moved past. Kilicdaroglu’s reinstatement came via judicial order rather than fresh internal election, leaving CHP loyalists governing a party most of its own lawmakers and voters are expected to abandon [1, 3].
• Their party just lost most of its seats overnight. CHP’s collapse from a major opposition force to 44 seats after the defections leaves remaining loyalists managing a shell of what was Turkey’s largest opposition party [3].
• They’re now cast as the obstacle, not the alternative. Refusing to call a new leadership congress is what triggered the split in the first place, leaving the CHP old guard blamed by former allies for fracturing the anti-Erdogan opposition [2, 3].
