EXCLUSIVE: In the goldfish bowl of royal life, there are very few people whom those at the very top can trust, and for King Charles, the list is even shorter.

Thankfully, though, the people he does have around him can be counted on for their dedication to duty, their tact and their iron-clad sense of discretion.

While this list includes the likes of his son, The Prince of Wales, and his brother, The Duke of Edinburgh, it is the female members of the Royal Family who provide the most solid basis for the King as he continues to navigate his hugely important role.

Despite Queen Camilla being firmly included as Charles’s sounding board and rock, another close relative takes the top spot as the monarch’s ultimate confidante.
