Prince Charles has described the birth of granddaughter Lilibet "Lili" Diana Mountbatten-Windsor as "happy news".
How the new baby affects succession – and the royals she bumps down the list
But Charles' comments on Tuesday were the first time a royal has spoken publicly about the baby.
The royal described the birth of his fifth grandchild – a first sibling for baby Archie – as "happy news" during a visit to a production plant for the Mini at Cowley near Oxford.
The new baby is the Queen's 11th great-grandchild.

But with the Sussexes living in California and amid troubled relationships with Harry's family, it is not known when or if the new addition will meet the Queen and the rest of the royals.
