In Video: Royal superfans flagged up as they await arrival of new baby

Royal fans have plenty to look forward to in 2018 and, with the imminent arrival of the Duke and Duchess of Cambridge's third child, the pavement outside the Lindo Wing of St Mary's Hospital in London's Paddington district is already well occupied.

Festooned with Union Flags and with other royal props, a group of superfans are ready for Kate's arrival and, hopefully, for the first public appearance of the child who will replace Prince Harry as fifth in line to the throne.

Terry Hutt, known as Union Jack Man, admits some people think they are mad but says others like what they are doing.
