New parents Prince Harry and Meghan Markle have shared the very first personal photo of their royal baby boy Archie.

Celebrating Father’s Day in the UK, a sweet snap was unveiled of the newborn wrapping his tiny hand around the Duke of Sussex’s finger, while being cradled by the 34-year-old royal.

The sepia coloured photo also showed the 6-week-old giving a peek-a-boo look out from his father’s arms.

Alongside the candid picture, a Father’s Day message was shared: "Happy Father’s Day! And wishing a very special first Father’s Day to The Duke of Sussex!"

It is suspected that this personal photo may have been taken by the Duchess of Sussex inside their Frogmore Cottage home.
