The 82-year-old head of state, who has been on the throne for half a century, canceled her appointments for the week. Queen Margrethe, who has been vaccinated against the coronavirus, was also diagnosed with Covid-19 in February this year, showing mild symptoms at the time. The half-century reign now makes her Europe’s longest-serving monarch after Elizabeth II, 96, who ruled for 70 years, died on September 8. Out of respect for the late British monarch, Margaret had asked her court to adjust the schedule for her own 50th anniversary celebrations earlier this month. Among the events he canceled at short notice were an appearance on the balcony of Amalienborg Palace to greet well-wishers and a carriage ride through Copenhagen. Margrethe was proclaimed queen in January 1972, a day after the death of her father, King Frederick IX, after a short illness. Queen Elizabeth’s funeral took place on Monday amid great worldview. Queen Margrethe was among hundreds of world leaders, current and former monarchs who attended the event. Other monarchs in London on Monday included those from the Gulf, while US President Joe Biden and France’s Emmanuel Macron were among the highest-profile political leaders. The event was widely watched across Britain and the world, with the BBC claiming 28 million people watched its coverage. Meanwhile, live footage of the Queen lying in state was streamed 25 million times to the BBC online, it said. (With agencies)
