In his first message delivered in Welsh, the Prince of Wales has wished the country a “Happy St David’s Day”.
William said he wanted “to celebrate Wales – its history, its culture, and its incredible people” in a pre-recorded video posted on social media on 1 March, the patron saint’s day.
It comes three days after he and his wife Kate toured Pontypridd and cooked Welsh cakes for a market stall holder.
William isn’t having formal lessons, but is known to be using the Duolingo app and has been learning some conversational Welsh.
The English translation of what the heir to the throne said in his message was: “Hello. Today, on St David’s Day, we come together to celebrate Wales – its history, its culture, and its incredible people.
“From its breathtaking landscapes to its language, Wales continues to inspire.
“Today, we will celebrate everything that is magical about Wales.
