Archive film shows Kate's great-great-great relatives

Footage of some of the Duchess of Cambridge's forebears from the time of the First World War has been discovered in archives of the British Pathe newsreels.

The video from 1915 shows Kate's great-great-great Uncle Sir Charles Lupton, the lord mayor of Leeds, visiting the Leeds Pals Battalion in the Yorkshire Dales.

Another video from 1927 shows Kate's great-great-great uncle and his wife Isabella greeting the Queen's aunt, Princess Mary, on a visit to Leeds.

Alastair White, general manager of British Pathe, said: "We knew we had many films of Prince William's family, but it was a real surprise to find that we also have the Duchess of Cambridge's ancestors and that they were meeting royalty."
