Prince George's registrar "received death threats" "Let's just say I had to have more than one attempt," said the registrar. It was a very hot day and I was flustered and trying to fill this thing in with Prince William sitting beside me. Ms Cathcart, who appears in a fly-on-the-wall documentary series this week charting the work of staff at Westminster Register Office in Marylebone, refuses to be drawn on the details of her mishap, but says she was relieved that registrars these days can get away with mistakes as they no longer work with bound registers. She explains how, in the pre-digital age, expert penmanship was regarded as essential for the forms registering births, marriages and deaths. "It used to be a requirement for the job," she says. That hasn't been the case for a long time - but obviously some people think it should be. The cameras record her heading off to Kensington Palace to register the royal birth to avoid the inevitable media circus that would follow a visit by Prince William to the Marylebone office. She said this break with protocol may explain why her handwriting failed to meet the exacting standards of some royal fans. While wedding certificates are still done by hand, births are mostly registered on computer these days. I certainly haven't written one out for a while.
