Catherine, Princess of Wales is set to be among those attending services to mark Armistice Day on Tuesday.
Catherine will be at a ceremony held at the National Memorial Arboretum in Staffordshire, with a two-minute silence at 11:00 GMT to commemorate the end of World War One and to remember those who have died in all wars since.
Her husband, the Prince of Wales, will also deliver a video message to young people, sharing his views on the importance of wearing a red poppy and to say that “remembrance is for everyone”.
William’s message to children across the UK is to be played out at the Royal British Legion’s Remembrance Assembly on Tuesday morning.
The virtual event brings together children aged between nine and 14 in schools, libraries, home education and other learning settings across the UK.
“Armistice Day is an important time for us to stop and reflect – it is a reminder that remembrance is for everyone,” the prince will say.
“When we remember, we connect with service in a personal way.
“We learn from the courage of others, and we carry their stories forward, so they are not forgotten.
“It’s not just about the past – it’s about shaping who we become in the future.
“Remembrance teaches us empathy, resilience and responsibility.
“And when we wear a red poppy or take a moment of silence, we are saying, ‘Thank you. We have not forgotten, and we will not forget’.”
Meanwhile, the service in Staffordshire will feature the reading of a specially commissioned poem by the arboretum’s poet in residence, Arji Manuelpillai.
“A Sonnet For Us All captures the stories etched into the hundreds of memorials within the National Memorial Arboretum, it invites people to listen, reflect and consider the emotion that was the inspiration for these sculptures,” Mr Manuelpillai said.
“These human connections, and the gentle responsibility to carry love forward, are themes that resonate not only with me, but also with HRH The Princess of Wales, for whom the importance of service and compassion lies especially close to the heart.”
Later on Tuesday, William will join the King and Queen at Windsor Castle where a reception will honour veterans who served in the Pacific during the Second World War.
The event, which the Duke of Edinburgh and the Duchess of Gloucester will also attend, continues the commemorations for the 80th anniversary of VJ Day – or Victory over Japan Day.
