On the morning of October 22, 2026, a ceremony for the presentation of credentials by heads of diplomatic missions to the President of the European Commission Ursula von der Leyen and the President of the European Council António Costa took place in Brussels. The event was part of protocol procedures traditionally accompanying the appointment of new ambassadors to the institutions of the European Union. Information about the ceremony was published in the European Commission's daily news bulletin, which contains a summary of current events and decisions concerning the activities of European institutions. The presentation of credentials is a standard diplomatic procedure confirming the official beginning of an ambassador's mandate in the receiving country. For the European Union, which unites many member states, such ceremonies are of particular significance, as they symbolize the development of the Union's international relations with third countries and international organizations. Details about which specific countries and missions were represented at this ceremony are not specified in the brief announcement; however, such events are regularly held in Brussels and reflect the current dynamics of the EU's diplomatic contacts with partners around the world.
