Noisy anti-monarchy protestors have gathered outside Westminster Abbey ahead of the Royal Family's arrival at today's Commonwealth Day Service. The King and Queen will be joined by the Prince and Princess of Wales, the Princess Royal and her husband Vice Admiral Sir Tim Laurence, and the Duke and Duchess of Gloucester for the annual service celebrating the Commonwealth.

Dozens of protestors carrying bright yellow placards have begun gathering outside, chanting through a megaphone. The large Republican banners read: not my King, down with the crown, abolish the monarchy and Charles, what are you hiding?
