Princess Danica, were the only members of the
House of Karađorđević who attended the funeral service of Patriarch Irinej at the

Easter, Philip visited Kosovo to support the
Serbian community there. He also became the first member of the House of Karađorđević after his grand-grandfather, King Alexander I, who travelled to
Prizren. He and his wife travelled there for a weekend visiting the
Orthodox Seminary,
Our Lady of Ljeviš Church,
Cathedral of Saint George, and

Han Pijesak, Bosnia and Herzegovina. They met with local authorities and took over the keys to the summer house of the Karađorđević family. The summer house was built by King Alexander I in the early 1920s and used by his family until 1941. Afterwards, the house was used for the command of the Ustaša Commissioner
Jure Francetić during
World War II. After the war, the house was commonly known as ''Tito's Villa'', although Yugoslav communist president
Josip Broz Tito never stayed there. Devastated by time, the summer house will be rebuilt and renovated as Prince Philip has agreed with local authorities and the
Government of Republika Srpska to fund it. According to some sources, the
Vidovdan Constitution was signed in the summer house. Furthermore, on 10 February, Prince Philip and his wife met with
Milorad Dodik, a Serb member of the
Presidency of Bosnia and Herzegovina. On 21 March 2022, Philip and his wife signed the ''People's initiative to ban the exploitation of lithium and boron'' in Serbia.
