Due to current coronavirus restrictions, several Books of Condolence have been set up online.
The Royal Family’s Twitter account said: “An Online Book of Condolence is now available on the Royal website for those who wish to send a personal message of condolence.
“During the current public health situation, Books of Condolence will not be available for the public to sign.
All you need to do, to sign the Royal Book of Condolence, is go to the website: https://www.royal.uk/
“The Royal Family ask that members of the public consider making a donation to a charity instead of leaving floral tributes in memory of The Duke.”
