CHARLES' LITTLE KNOWN STARS

They are the royal family's A-team - the inner circle of working royals who made the cut to appear in one of a handful of official photos released to celebrate the King's coronation. While most of the family members posing for photographer Hugo Barnard are well-known, some are less familiar. Here's a guide to those you may not know and why they made it into this historic shot...

THE DUKE OF KENT

Prince Edward, Duke of Kent, 87, made P the line-up thanks to the fact he's a working royal who has carried out thousands of engagements over many decades on behalf of Elizabeth II, and now represents the King.

His father, Prince George, Duke of Kent, was the younger brother of the Queen's father, George VI, and Edward was also related to Prince Philip through his mother, Princess Marina of Greece and Denmark. Philip and Marina's fathers were brothers.

Edward's father died, aged 39, in a plane crash in Scotland in 1942 and Edward became Duke of Kent when he was six. By 16, he was carrying out official duties after his cousin Elizabeth became Queen.

Edward served in the army for more than 20 years, during which time he was posted in Cyprus and Northern Ireland. Since retiring in 1976, the duke has been a full-time working member of The Firm. He was appointed as a special trade envoy for the UK and was the first member of the royal family to visit China. In 2015, he received the Dresden Peace Prize for his "contribution to British-German reconciliation".

Over the years, he's been involved with more than 140 charities and organisations, including head of the Football Association, the Scout Association, the All England Lawn Tennis and Croquet Club, and the Commonwealth War Graves Commission.

In 1961, he wed Katharine Worsley. She caused something of a scandal in 1994 when she converted to Catholicism, but because the switch in religions happened after her marriage, it did not cause the duke to lose his place in line to the throne, which is 40th.
