‘Queen Mary’ is central! The Australian-born wife of Danish Prince Frederik stars as the royal family gathers for the annual New Year’s dinner, a day after reigning Queen Margrethe abdicated ‘to put her wayward son on the throne and save his marriage’

Queen Margrethe of Denmark has shocked royal watchers around the world and ended her 52 years on the throne by abdicating.

The move means that her son, formerly Crown Prince Frederik, and his wife Mary are now king and queen.

Her choice of date makes her decision particularly public, as the Danish Royals held a New Year’s Eve dinner and banquet tonight.

While Queen Margrethe appeared cheerful as she arrived at the event at Amalienborg Palace in Copenhagen, it was the new queen who stole the show.

She arrived at the event with her husband, the new king, looking radiant in a maroon velvet dress and elaborate tiara.

The shocking abdication follows a tumultuous moment for the family:
