This year’s event takes on added significance as it marks the 100th anniversary of the end of the First World War.
The 97-year-old officially retired from royal duties in May 2017 but he did attend last year’s service in Whitehall.
Along with her Majesty the Queen the pair watched the war memorial from the Foreign and Commonwealth Office balcony.
During the service Prince Philip appeared at times unsteady on his feet and had trouble standing.
For the second successive year Prince Charles will lay a wreath of poppies to commemorate Britain’s war dead on the Queen’s behalf.
As head of the Armed Forces, Remembrance Sunday is seen as a significant annual event for the Queen who will join the nation for two minutes silence at 11am.
After the service, 10,000 people, chosen by ballot, will have the opportunity to pay their respects by taking part in the Nation’s Thank You procession past the Cenotaph.
The annual Remembrance Day service is expected to be attended by all senior royals including Prince Harry and Meghan, the Duchess of Sussex as well as Prince William and Kate, the Duchess of Cambridge.
This will be the Duke and Duchess of Sussex’s first public appearance in the UK since their 16-day tour of Australia, New Zealand, Tonga and Fiji.
After the memorial at the Cenotaph senior royals including the Queen, Harry and Meghan will attend a special service to mark the Centenary of the Armistice at Westminster Abbey.
Last month Prince Philip surprised many by appearing at the wedding of his grandchild Princess Eugenie to Jack Brooksbank on October 12.
He also did not miss the wedding of Meghan and Harry in May despite having a hip operation one month prior to the big day.
Yesterday the Duke of Edinburgh was spotted as he took his horse out for a ride in the grounds of Windsor.
He was seen riding solo at the front of his carriage, with two stable-women sat behind.
The Queen a keen race goer was also seen riding one of her steadfast horses.
