King in Council (Sweden)

King in Council, or Royal Majesty, (most formally Konungen i Statsrådet, but a term for it most often used in legal documents was Kunglig Majestät or short form Kungl.Maj:t or K.M:t. in Swedish) was a term of constitutional importance that was used in Sweden before 1975 when the 1974 Instrument of Government came into force.

Royal Majesty denoted several functions, but most importantly, it was the commonly used term that designated the supreme executive authority under the 1809 Instrument of Government: where the King made all decisions of state in the presence of his cabinet ministers. The 1974 Instrument of Government removed the Monarch from all exercise of formal political powers and created its successor: the Government (Swedish: Regeringen) chaired and led in all aspects by the Prime Minister.
