Kai Wegner has been CDU leader in Berlin since May 2019. The vast majority of his party has decided that he should continue.
Berlin’s governing mayor Kai Wegner remains CDU chairman in the capital. At a party conference in Neukölln on Saturday, 249 delegates voted for the 50-year-old, who had no opposing candidate, with 10 votes against and 4 abstentions. This corresponds to an approval of 94.7 percent. The CDU spoke of around 96 percent because, unlike other parties, it does not take abstentions into account.
Wegner has been CDU leader in Berlin since May 2019. When the House of Representatives election was repeated in February of this year, he led the CDU back to power after many years in opposition: it won the election and has been governing together with the SPD since April. With Wegner, the party has a governing mayor in Berlin for the first time in more than two decades.
