There will be though feverish speculation over whether the newborn is to have a bris. At least as far back as Victorian times, circumcision was de rigueur for royal princes. According to Hanoverian tradition, the procedure was carried out not by the royal physician but a Jewish mohel. An entire generation of Jewish men is still proud to say that they were attended to by the same practitioner as Prince Charles. However, when it came to the next generation Diana, as she was to do so many times over the years, rebelled against the queen's wishes when her sons were born. If a multitude of sources are to be trusted, then William was circumcised in a medical procedure (according to some versions of his own choice at a much later date) and Harry's foreskin is still intact. No details have yet been released regarding the plans regarding the new prince's private part but if past experience is anything to go by, we will know sooner or later.
