"I love the photo of the undercover ducks!!!" one royal fan wrote, while another added: "The person responsible for Clarence House social media today should definitely get a promotion!"

Today, The Prince of Wales, in his role as Royal Patron of the Intelligence Services, visited @gchq to mark #GCHQ100. During the visit, His Royal Highness met representatives of community groups that GCHQ work closely with, and staff who work at the headquarters. The Prince also had the chance to look at artefacts in the GCHQ Museum, which included intelligence reports and the Royal Codebook. To mark the opening of the GCHQ Centenary Garden, HRH watched a flyover by @rafredarrows and planted a tree. The garden features 'spy ducks' in the pond and a 'hotline' telephone box, which has been converted into a greenhouse for chillis.‪ In a speech to the GCHQ workforce, HRH said: "Looking back at GCHQ's unfailing ability to rise to the challenges of its time gives me every confidence that this country, our freedom and our way of life, will continue to be well served by all of you, no matter what comes at us."‬ 🔍

The 70-year-old also gave a speech during his visit.

"To you, walking in past the razor wire each day becomes routine," he said. "But I hope that you will never lose sight of the fact that you are part of an extraordinary, world-leading organisation that has achieved remarkable things during its proud one-hundred-year history, and which will continue to play an indispensable role over the century to come."

It's been a busy month for Charles and Camilla.

This morning, The Duke and Duchess of Sussex's son, Archie Harrison Mountbatten-Windsor was christened in the Private Chapel at Windsor Castle at an intimate service officiated by the Archbishop of Canterbury, Justin Welby. The Duke and Duchess of Sussex are so happy to share the joy of this day with members of the public who have been incredibly supportive since the birth of their son. They thank you for your kindness in welcoming their first born and celebrating this special moment. Their Royal Highnesses feel fortunate to have enjoyed this day with family and the godparents of Archie. Their son, Archie, was baptised wearing the handmade replica of the royal christening gown which has been worn by royal infants for the last 11 years. The original Royal Christening Robe, made of fine Honiton lace lined with white satin, was commissioned by Queen Victoria in 1841 and first worn by her eldest daughter. It was subsequently worn for generations of Royal christenings, including The Queen, her children and her grandchildren until 2004, when The Queen commissioned this handmade replica, in order for the fragile historic outfit to be preserved, and for the tradition to continue.

The royal duo recently returned from a trip to Wales and attended grandson Archie Harrison’s christening on Sunday.
