Isla Phillips was born on Thursday at Gloucestershire Royal Hospital, Gloucester, to Peter Phillips and wife Autumn, weighing 7lb 4oz. Perhaps in a nod to her great-grandmother’s Diamond Jubilee year, she has been given the middle name Elizabeth.
She is a second daughter for Mr Phillips, who was present at the birth, and his wife. Her older sister Savannah was born in 2010.
The Queen’s press secretary said the Queen was delighted at the news.
Isla Elizabeth will be 13th in line to the throne.
