Thuringia coalition holds as BSW state branch resists federal demand to oust Voigt

Division between Berlin and Erfurt

Thuringia Minister-President Mario Voigt and Deputy Premier Katja Wolf moved on Tuesday to stabilise Germany's only three-party coalition uniting the Christian Democratic Union (CDU), the Sahra Wagenknecht Alliance (BSW), and the Social Democratic Party (SPD). The coalition faced pressure after the BSW federal executive in Berlin passed a resolution demanding that its Thuringian state chapter exit the government and push for a non-partisan premier. BSW national leaders, including Sahra Wagenknecht, Fabio De Masi, and Amira Mohamed Ali, urged the local branch to end cooperation before upcoming regional elections. Wolf, who also serves as Thuringia's finance minister, announced that the state executive will convene a special party congress in the coming weeks to resolve the internal conflict. She openly condemned the federal board's actions as external interference against an otherwise functional state administration.

That Thuringia is being used as a plaything is very frustrating.

The caucus vote and parliamentary math

On Monday, the BSW parliamentary group in Erfurt formally voted on whether to remain in the regional government. Thirteen of the fifteen BSW state lawmakers voted in favour of staying in the coalition with the CDU and SPD. The two dissenting lawmakers, Anke Wirsing and Sven Küntzel, did not attend the ballot, with Wirsing citing a medical appointment and Küntzel a follow-up commitment. The governing alliance holds exactly 44 of the 88 seats in the Thuringian state parliament, relying on an informal consultation procedure with the opposition Left party to pass legislation. While Wirsing stated that she would not systematically oppose coalition bills, she insisted that Voigt should step down. Küntzel confirmed that he would decide his votes issue by issue, adding that he would not support Alternative for Germany (AfD) leader Björn Höcke.

Disputed leadership and plagiarism findings

The immediate catalyst for the federal BSW leadership's demand was the decision by the Chemnitz University of Technology (TU Chemnitz) to revoke Voigt's doctoral title following a plagiarism investigation. Voigt was unsuccessful in his administrative objection against the university's revocation, though his legal counsel announced plans to file a formal lawsuit against the ruling. In response to the academic controversy, Höcke announced that the AfD planned to table a constructive vote of no confidence against Voigt in the Erfurt parliament. Höcke proposed Wagenknecht as a candidate for minister-president, a suggestion she rejected. Voigt dismissed calls to resign, stating that the state government remained fully focused on practical policy matters.

We will not let ourselves be driven apart and make Thuringia a plaything of party-tactical manoeuvres.

Broader eastern state election strategy

The dispute in Erfurt intersects with a broader debate within the BSW ahead of two eastern state elections scheduled for September 2026. BSW lead candidates Peter Schabbel in Mecklenburg-Western Pomerania and Thomas Schulze in Saxony-Anhalt issued a joint statement backing the federal leadership's position. They called for an end to the traditional political firewall against the AfD and supported replacing party-led cabinets with non-partisan prime ministers governed by fluctuating legislative majorities. In Saxony-Anhalt, where the state election takes place on 6 September, the state domestic intelligence agency classifies the AfD as confirmed right-wing extremist, yet polls show the party led by Ulrich Siegmund in a strong position. Mecklenburg-Western Pomerania holds its vote two weeks later on 20 September.
