The Queen has asked Prince Charles to step in and fulfill her duties at a ceremony set to be held on Remembrance Sunday.
Breaking with tradition, the ceremony will see Her Majesty observing from the balcony instead of taking part and laying a wreath in person.
The Cenotaph ceremony is a significant event in the life of the country as the Queen leads the nation in remembering those who have died in world wars, both at home and around the world.
Charles taking over this role on behalf of the head of state will be a significant moment in his service to the monarch.
Earlier this summer, claims had been made that the Queen was preparing for abdicate the throne and make Charles king. Her majesty has revealed to her inner circle that if she is still on the throne when she turns 95-years-old she will seek legislation to grant her eldest son the power to reign while she is still alive.
"Her Majesty is mindful of her age and wants to make sure when the time comes, the transition of the Crown is seamless," according to a senior former member of the Royal Household.
Queen Elizabeth is the longest-serving monarch following her Coronation in 1953 after her father's death.
"In a way, I didn't have an apprenticeship. My father died much too young and so it was all very sudden ... taking on and making the best job you can," the Queen said.
During her reign, the Queen has only missed the opportunity to pay her respects in person with a wreath of poppies at the central London war memorial on six occasions; four of which because she was overseas. The other two were during her pregnancies in 1959 and 1963.
Prince Charles has laid the wreath for his mother at the ceremony during two occasions when she was overseas.
So what is the reason she has him taking over this time?
