The friends who will be part of Kate Middleton's elite baby club

Peter and Autumn Phillips

Children: Savannah, two and a half, and Isla, one

William has a great deal of respect for his cousin Peter, who keeps a low profile working in sports sponsorship and management.

The two couples often meet at equestrian events when they are supporting Peter's sister, equestrian champion Zara.

Peter's hands on style as a dad will be an inspiration to the future King.
