Before the 2025 federal election, the SPD, CDU, CSU, Greens, FDP and Die Linke agreed on rules for a fair campaign. They wrote: Wir debattieren im Respekt voreinander, verzichten auf persönliche Herabwürdigungen. We debate with respect for one another and do without personal disparagement. The agreement also rules out attacks on the personal or professional circle of politicians. The BSW decided not to take part. The AfD was not asked.
