For the first time in 70 years, the United Kingdom and the world are preparing for the coronation of a British monarch. But what do we know about the role, function and character of our new King? Join Telegraph columnist Simon Heffer as he speaks to those who can give a glimpse of Charles III: friends, former staff, and our own royal reporters and writers. 

The series will explore three arenas:

The King and his crown; how a Prince of Wales who spoke his mind becomes a King who cannot.

The King and the world; how the King takes on the role as the UK's figurehead and leading ambassador, and what he can do for the country in its international relationships and in his role as head of the Commonwealth.

The King and his people; will Charles III bring a new style to the monarchy when it comes to relating to his people?
