The Prince of Wales has sent a message to the Wales rugby team after they were crowned Six Nations Grand Slam champions.

Charles, who is overseas on a tour of the Caribbean, praised the squad for their “famous victory”, and congratulated them on their “brilliant performance”.

The heir to the throne added that their achievement made him “extremely proud of Wales”.

The squad’s success culminated in a 25-7 victory over Ireland in Cardiff on Saturday, with the Duke of Cambridge presenting the trophy to captain Alun Wyn Jones.
