Aðalsteinn Leifsson has decided to step down from his position as an assistant to the Icelandic Minister of Foreign Affairs, Þorgerður Katrín Gunnarsdóttir, after serving for just one year. His resignation comes after he ran for the leadership nomination of Viðreisn for the upcoming municipal elections but lost out to Björg Magnúsdóttir. Leifsson expressed gratitude for the collaborative experience he had while working in the Ministry of Foreign Affairs, highlighting the significant trust placed in him by the Minister, which allowed him to lead the creation of Iceland's first formal defense and security policy.

During his tenure, Leifsson participated in various initiatives and has played a crucial part in shaping the country’s approach to defense and security matters. He noted that the development of the policy exceeded even the most optimistic expectations in terms of progress and effectiveness. Leifsson's decision to resign seems to be influenced by his desire to focus on his political ambitions within the Viðreisn party, which may suggest a shift in his career aspirations towards more direct electoral politics following his considerable contributions to foreign policy development.

Leifsson also mentioned that he has been asked by Þorgerður Katrín to continue supporting the policy work as a substitute member of parliament, which indicates that despite stepping down from his current role, his influence and involvement in Iceland's political landscape will likely continue, particularly in areas concerning national defense and security.
