King Frederik put in a low-key appearance at Wimbledon over the week as he took a break from his royal duties.
The Danish monarch, 57, was spotted on No. 1 Court at the tennis tournament as he watched the match between Chile's Nicolas Jarry and Britain's Cameron Norrie.
Frederik sported a grey suit, a white shirt and a grey and pink striped tie for his appearance, but he was not accompanied by his wife, Queen Mary.
The couple are both said to be fans of the sport, with Australian-born Mary seen picking up a tennis racket on several occasions over the years.
According to the Danish royal family's calendar, the king is on holiday until 13 July, with his son, Crown Prince Christian, 19, acting as a regent in his father's absence.
Mary currently has no engagements in her diary, so it's likely that the couple are taking some time away from the public eye until their annual summer retreat to Gråsten Palace in South Jutland.
In August, Frederik and Mary will also embark on a royal tour around some of Denmark's municipalities onboard the Royal Ship Dannebrog.
Last appearance together
The king and queen stepped out last week to attend a dinner and ceremony at Aarhus Town Hall to mark Denmark's takeover of the EU presidency.
King Frederik donned a smart suit for the occasion, while Queen Mary cut an elegant figure in a red Max Mara jumpsuit in a nod to the Danish flag.
The EU presidency rotates between the member states, and Denmark is now taking over the presidency of the Council for a six-month period.
On Friday, the monarch also tried his hand at a number of activities as he attended the DGI National Convention 2025 in Vejle, which is Denmark's largest sports festival, held every four years.
