September 29H.M. The Queen holds a Government Dinner at Fredensborg Castle (20:00)
The queen is the host, and it is stated that Crown Prince Frederik and Crown Princess Mary will also participate. Her Majesty usually invites the Council of State, which is comprised of the government, the Secretary of State, and typically also some staff at the court to a distinguished dinner.
The Council of State deals with all laws and important government measures, and the Royal House describes it as follows: "H.M. The Queen chairs the meetings of the Council of Ministers (chaired by all ministers). HRH the Crown Prince has also had a seat in the Council of State since he came of age. The main content of the meetings is confirmation of the bills passed by the Folketing and submission to The Queen's of the bills that the government intends to put forward In practice, it is often necessary to submit cases to the Queen outside the Council of State because the case can not wait for the next Council of State meeting. at the next meeting of the Council of State, where the matter is resubmitted. The Council of State is held as needed and currently about six times a year. The meetings are held on Tuesday morning and typically take place in the Council Chamber at Christiansborg Castle".
Attempts are made to organize it so that a Government Dinner is held once in each term of government, but for various practical reasons, this may not always be possible. Due to the ravages of the corona pandemic over the past year and a half, the Prime Minister's Dinner, like many other events, has been impossible to carry out, but now that the restrictions have been eased, Prime Minister Mette Frederiksen and the government can gather for a festive evening.
Interesting, they couldn't have Marie join for that stint. She's also in DK for that week. I guess, she is now on the outskirts of the RF.
