Theirs is an understated job but one that is of utmost important to Her Majesty The Queen.
With a busy schedule and a day-to-day routine to manage, the monarch is supported by a number of ladies-in-waiting, some of whom work on a daily basis, some of whom only appear on ceremonial occasions.

Lady Susan has been by the Queen's side since the birth of Prince Andrew in 1960 and is now one of her most trusted friends. Notably, the 81-year-old is also close to Prince Charles and is a godmother to Prince William.
A constant presence in royal life, Lady Susan has largely remained out of the spotlight, but was famously photographed in 2012 draping a pashmina over the Queen's shoulders as they sailed down the Thames in the pouring rain on the Royal Barge for the Jubilee pageant.
