The King will lead the UK in a two-minute silence on Remembrance Sunday to remember those who died in conflict. Charles will be joined by members of the royal family and senior politicians who will lay wreaths at the National Service of Remembrance at the Cenotaph in London.
About 10,000 veterans are set to take part in the Royal British Legion's march past, with more than 300 different Armed Forces and civilian organisations represented. People of all ages will be among those marching, from bereaved children and military cadets through to some of the last surviving veterans of the Second World War.
Political and royal tributes
Prime Minister Andy Burnham said: "I'm incredibly proud to be honouring those whose sacrifice continues to protect our way of life to this day."
"Remembrance Sunday gives us an opportunity, not only to mark that sacrifice and offer our gratitude, but also to reflect on its significance. To reflect on the selflessness and courage it takes to commit your life to protecting others," he added.
"I want to offer my personal thanks to those who served and those who continue to serve in our Armed Forces communities to this day."
Defence Secretary Wes Streeting also spoke ahead of the service, recalling his childhood memories of his grandfather and great-grandfather's war medals. "Defence runs in my blood and I feel intently the importance of remembrance to those who have served and their families," he said.
Veterans share their stories
RAF veteran Steve Hooper, 43, who served as a mechanical transport driver during the Iraq War, will be marching with the Invictus Games Alumni group. He described struggling with sleep and flashbacks after his service as an ambulance driver in Iraq.
"If it wasn't for the support I received from the Royal British Legion through the Invictus Games, I don't know where I'd be today," he said. "I am proud to be marching alongside my fellow team members as we reflect on our recovery journeys and remember all those who weren't as lucky."
At 103 years old, Women's Land Army veteran Annie Duplock will be taking part in the march past for the first time. She joined the Land Army in 1940 at age 16, having lied about her age to enrol, and spent four years working on a farm in Leicestershire milking cows, ploughing fields and harvesting crops.
"I feel very honoured to be taking part in the parade and to represent the Land Girls. I'm very excited, although a little apprehensive as I don't quite know what to expect," she said. "I think it will be a very emotional day, bringing back memories of all those who didn't return home."
