Denmark’s former monarch, 86-year-old Queen Margrethe, has been released from hospital after undergoing an angioplasty procedure last week, the palace said on Tuesday.”Her Majesty Queen Margrethe was discharged from Rigshospitalet today and is returning to Fredensborg Palace,” it said in a new statement on Tuesday.”In the coming period, Her Majesty will need rest,” it said, adding that a planned theatre engagement on May 23 had been cancelled.The queen underwent “a balloon dilation of a coronary artery” at Copenhagen’s main Rigshospitalet hospital, the palace said in a statement on 15 May.The former sovereign reigned in the Scandinavian country for 52 years before passing the throne to her eldest son Frederik in January 2024.Hugely popular among Danes for subtly modernising the monarchy, Margrethe has faced multiple health problems in recent years.She had long vowed that she would never abdicate, but major back surgery in 2023 led her to change her mind.Margrethe is known for her significant interest in the arts.As a designer she won a Danish film award for best costume in 2024 and translated Simone de Beauvoir’s “All Men Are Mortal” under a pseudonym with her late husband, Prince Consort Henrik.She has also illustrated several books, including JRR Tolkien’s “The Lord of the Rings.”
