On the occasion of a royal birth, a statement of witness is made in accordance with tradition. This is done on the day after the birth, unless the birth takes place on a Saturday, in which case the statement of witness is made on the following Monday. At the same time as the statement of witness, the four witnesses see the newborn child.
The Speaker, the Prime Minister, the Marshal of the Realm and the First Lady of the Court are the witnesses. The statement of witness is signed and sealed by these witnesses.
The witnesses for Prince Oscar were the Speaker Urban Ahlin, Prime Minister Stefan Löfven, Marshal of the Realm Svante Lindqvist and First Lady of the Court Kirstine von Blixen-Finecke.
