North Macedonia's newly elected president, Gordana Siljanovska Davkova, was sworn into office on Sunday and immediately reignited a diplomatic spat with Greece. During the ceremony, she referred to her country as Macedonia rather than by its constitutional name - North Macedonia. This prompted Greece's ambassador to Skopje to leave the inauguration. Davkova’s office said she has the right to use the name Macedonia as an act of self-determination. The decades-long dispute between the two neighbours was resolved in 2018 with the signing of the historic Prespa agreement. Since then, Macedonia has been known as the Republic of North Macedonia.
