Danes are encouraged to celebrate Queen Margarethe II’s 80th birthday in their homes after original plans were cancelled, courtesy of the coronavirus.

According to Denmark.dk on Twitter, the Danish Broadcasting Corporation (DR) invites Danes to sing for Queen Margrethe in their homes with various well-known performers leading the ‘choir’ throughout the day.
People are also encouraged to make a traditional Danish birthday cake – a lagkage’ (layer cake) to mark this special occasion.
