King Charles and the other royals will be exposed to more anti-monarchy protests due to their "hard to define roles", a historian has claimed.
Last week, the monarch came face-to-face with anti-monarchy protestors who held up signs saying "Not My King" in Milton Keynes.
It came just days after a lone protestor was also bundled away by police after disturbing a walkabout by the Prince and Princess of Wales in Cornwall.
