Berlin election results increase pressure on the traffic lights. The 2021 federal election was repeated on Sunday in around a fifth of Berlin's electoral districts due to organizational breakdowns at the time.

Around 550,000 capital city residents were allowed to vote again - only around one percent of those eligible to vote nationwide. The trend was clearer in the districts where the vote actually took place: there, the SPD and FDP lost significantly, while the CDU and AfD gained significantly. The AfD's strong performance and low voter turnout are warning signs.
