Queen Mary has taken on an important role this weekend as she steps up after Queen Margrethe's hospitalisation.
It was announced on Friday that the former monarch, 84, had been discharged from hospital having suffered a fall at her Fredensborg Palace home. In the meantime, it has been reported that King Frederik's wife, 52, will act as regent from 20 to 22 September as he spends time out of the country.
The role is a royal first for the mother of four as it is the first time Mary has acted as regent since assuming the title of Queen at the beginning of the year.
Regent is a role that requires a person to step in to govern the state when the monarch is unable to perform their duties. While King Frederik spends time abroad, Mary will step into his shoes as her son Crown Prince Christian did in January when he signed his first law upon his father's trip to Poland.
Queen Mary's previous tenures as regent
It isn't the first time that Queen Mary has fulfilled the monarch's duties.
In 2019, The Royal House announced that then-Crown Princess Mary signed a declaration in a Council of State gathering that stated she would act "in conformity with the Constitution in the presence of The Queen, His Royal Highness The Crown Prince, and the government" should she be the most senior royal in the country at the time.
"As acting regent, The Crown Princess will, from now on, be able to attend to The Queen’s duties as head of state when The Queen and The Crown Prince are prevented from doing so, for example during a stay abroad," the official announcement stated.
According to Danish publication B.T., during her previous tenure, Mary ratified bills as she became the second non-Dane to become a rigsforstander (regent) following Queen Ingrid.
Queen Margrethe's hospitalisation
Queen Mary's increased responsibilities fell just as her mother-in-law was discharged from Rigshospitalet.
"On Wednesday evening, Queen Margrethe was admitted to hospital after a fall, which unfortunately resulted in an injury which concerned the vertebrae of the neck as well as a fracture in the left hand," an official statement read.
"As a result of the fall, the left hand is now in a plaster cast, and The Queen will need to wear a stiff neck collar in the coming months," it continued.
