Jens Spahn resigned as chairman of the CDU/CSU parliamentary group after facing sustained criticism from within his own party for having a child via surrogacy in the United States, a practice the CDU officially opposes and that remains illegal in Germany. Chancellor Friedrich Merz and CSU leader Markus Söder have agreed on Thorsten Frei, currently head of the Chancellery, as his successor, with a formal vote expected in a special parliamentary group session next week. The swift move aims to contain the damage from a controversy that, according to party officials, has undermined the conservatives' credibility, particularly among their base.

Within the CDU, the reaction to Spahn's personal decision exposed a rift between the party's official moral conservatism and the private choices of its leaders. Local politicians from North Rhine-Westphalia to Mecklenburg-Vorpommern described the episode as "preaching water and drinking wine," with many arguing the resignation was inevitable. The controversy also reignited a broader debate on surrogacy legislation, with some legal experts and opposition Greens calling for liberalisation, while CDU figures such as former party leader Armin Laschet defended the current ban. Meanwhile, the leadership vacuum has intersected with a parallel dispute over the party's "firewall" against cooperation with the Alternative for Germany (AfD). Saxony's Minister-President Michael Kretschmer, a CDU deputy federal chairman, declared that "anyone still talking about firewalls has failed to recognise the signs of the times," arguing that the political arithmetic in eastern states necessitates dialogue with all parties, including the AfD. His remarks drew sharp rebukes from the SPD's youth wing and from within his own party, with federal CDU leaders reiterating their refusal to collaborate with the far right.

Viewed from Berlin, the twin crises over Spahn and the firewall threaten to erode the CDU's electoral standing just weeks before state elections in Saxony-Anhalt and Mecklenburg-Vorpommern, where the AfD is polling strongly and could emerge as the largest party. Party strategists fear that the perception of hypocrisy on surrogacy and mixed signals on dealing with the AfD will alienate both conservative and centrist voters. For Chancellor Merz, who has struggled with low approval ratings, the removal of Spahn removes a potential internal rival but also exposes the fragility of his coalition with the SPD. Merz has indicated he may use the opportunity to reshuffle his cabinet, though no immediate changes have been announced. The episode also highlights the CDU's ongoing difficulty in reconciling its traditional values with the personal lives of its modernising wing, a tension that analysts in Brussels and other European capitals see as emblematic of centre-right parties across the continent grappling with social change and the rise of nationalist challengers.

The CDU/CSU parliamentary group is scheduled to hold a digital meeting with Merz and Söder on Wednesday afternoon to discuss the succession plan. Frei's appointment is expected to be confirmed without significant opposition, given his reputation as a trusted Merz ally and skilled parliamentary manager. The broader question of who will replace Frei as head of the Chancellery remains open, as does the potential for a wider government reshuffle. In the eastern states, CDU candidates are bracing for a difficult campaign, with some local officials privately acknowledging that the Spahn affair has handed the AfD a potent line of attack. The state elections in September will serve as a critical test of whether the CDU can maintain its firewall without ceding ground to the far right, or whether Kretschmer's call for pragmatic engagement gains traction.
