The Duke of Cambridge has sent a letter to the Irish Guards, expressing his pride at the "grit and determination" they have shown over the last year.
Wishing the regiment a Happy St Patrick's Day, Prince William, who is the Colonel of the Irish Guards, praised their work at mobile coronavirus testing units, on deployments overseas and their overall "unwavering commitment" to their country.
In the letter, he said: "Sadly COVID restrictions mean that we cannot be with you this year, but it has been heartening to hear about the important work that you have been doing to support the response to the pandemic across the UK."
William added: "As your Colonel, I could not be more proud of the grit and determination displayed over the last 12 months."
Traditionally, the Duke and Duchess of Cambridge attend the Irish Guards' St Patrick’s Day parade each year in London but were unable to do so this year due to coronavirus restrictions.
A ceremony to mark the day still went ahead however and 1st Battalion Irish Guards' new regimental mascot was presented with a traditional shamrock.
Nine-month-old Irish Wolfhound Turlough Mór – known as Seamus to his colleagues – was inspected at Wellington Barracks, central London, in what was his first official ceremony.
The Duke, alongside the Duchess, also joined world leaders in wishing the Irish a Happy St Patrick's Day in a special video greeting.
William and Kate appeared in the video, as did US President Joe Biden, Canadian PM Justin Trudeau and New Zealand’s leader Jacinda Ardern, among others.
