Zara Tindall might not have a title, but the Prince and Princess of Wales once granted her a role that could have a huge impact on the monarchy's future. In 2013 the Prince and Princess of Wales made her one of Prince George's godmothers and she's the only Royal Family member to be a godparent to any of their children.
This highlights their trust in Zara and expert Robert Jobson believes her grounding influence on 13-year-old George is key. Speaking recently to the Daily Mail, he explained, "In the autumn he goes up to Eton. The apparatus that makes a king is already built around him. The school. The staff. The gaze tightening by degrees until one day he notices it, and it is too late to mind."
