Wegner has been leading a coalition government of the CDU and SPD in Berlin since 2023. Recent polls indicate a decline in support for the CDU compared to the previous election, which was necessitated by a ruling from the Berlin Constitutional Court that mandated a repeat of the 2021 election due to significant electoral irregularities. Despite facing criticism for his crisis management during a widespread power outage in the capital, Wegner received backing from the CDU. This announcement was broadcast on Deutschlandfunk on June 10, 2026.
