Björn Seibert is leading Ursula von der Leyen’s election campaign as the lead candidate of the Christian Democratic party family EPP in the European elections. The 43-year-old civil servant, who has been Head of Cabinet of the Commission President since 2019, is taking unpaid leave for the election campaign. His hiatus as Head of Cabinet ends on election night on June 9. He will then immediately resume his position in the Berlaymont building.
