The Queen, the Duke of Edinburgh, the Prince of Wales and his wife Camilla, the Duchess of Cornwall, commemorated Commonwealth Day at Westminster Abbey.

The BBC reported that singer Laura Wright performed "Stronger as One" for the Queen.

According to the East Anglian Daily Times, the Queen spoke on connecting cultures and described how the Commonwealth provided a great "understanding" for cultural differences. The annual message was delivered to over two billion Commonwealth citizens across the world.

"To support this theme, a special song has been composed for the Commonwealth, Stronger as One. There are any number of ways in which that single piece of music alone can be played or sung anywhere in the Commonwealth. And by sharing the same music with our own personal interpretations and contributions, the wonderful human attribute of imagination is nourished, and we gain insights of understanding and appreciation of others," the Queen elaborated.
