King Frederik and Queen Mary's royal household shared a major announcement about their son Crown Prince Christian's future plans after the Danish heir completed an intense military exercise.

The 19-year-old royal enrolled in military training with the Gardehusarregimentet (Guard Hussar Regiment) at the Antvorskov barracks in Slagelse in February.

After completing the traditional, arduous four-day REX tour last Thursday, Christian is now a Guards Hussar.

A statement released by the Danish royal palace on Monday read: "In connection with serving his military service with the Guard Hussar Regiment, the Crown Prince has now also been admitted to the Lieutenant's Training Course.

"The training starts in early August 2025 and lasts one year plus a subsequent period of practical service as a platoon leader.

"The Crown Prince will complete his ongoing military service with the Guard Hussar Regiment at the end of May."

Christian is following in the footsteps of his father, King Frederik, who spent much of his early career in the military. Frederik served in the infantry regiment of the Royal Life Guards and the Royal Frogmen Corps, an elite special forces unit within the Danish Navy.

After graduating from high school last summer, Christian spent three months in East Africa from September to December, where he was involved in the day-to-day running of two farms and was given an insight into conservation.
