HMS Lancaster has sent a congratulatory message to The Duke and Duchess of Cambridge on the birth of their new daughter.
Sailors standing on the flight decks of Type 23 frigate HMS Lancaster spelt out the word ‘sister’.
Meanwhile the Type 45 destroyer HMS Dragon spelt out the word ‘brother’.
Both are Portsmouth-based ships which are currently deployed in the Atlantic.
HMS Lancaster, known as the ‘Queen’s Frigate’, also sent a message of congratulations to the Queen on the birth of her youngest great-grandchild.
