An online Book of Condolence has been a launched to enable people to pay their respects to the Duke of Edinburgh in a Covid-19 coronavirus safe way.
As part of Government guidelines, traditional Books of Condolence will not be available in public buildings for people to sign in person.
The official 'Guidance for the Period of National Mourning' also asks the public not to lay flowers or other memorial items such as candles, messages and mementoes, at Royal Residences or other public spaces.
People are also asked not to visit Royal Residences or gather in public at this time, and to continue to follow all covid regulations.
However, the website www.princephilipcondolences.co.uk allows members of the public to pay their respects to Prince Philip in a Covid compliant way.
Within a few hours of its launch, nearly 9,000 people signed the book, which our publishers - Reach PLC - hope will offer some comfort to the Queen, the rest of the Royal Family, and all whose lives have been touched by the Duke.
The website says: "Prince Philip, the Duke of Edinburgh, died aged 99 after decades of dedicated service to the country and his family. The longest ever serving royal consort, Prince Philip was married to Her Majesty Queen Elizabeth for more than 70 years.
"As well as being the rock to the Queen, Prince Philip also changed the lives of millions of people around the world through his Duke of Edinburgh's Awards.
"And his tireless work for the World Wildlife Fund ensured the plight of endangered animals and the need to conserve the natural world has stayed at the forefront of people's minds for many years.
"His death at the age of 99 on Friday, April 9, saw an outpouring of grief from all corners of the globe.
"Here you can add your thoughts, wishes and memories to our lasting online memorial to the Duke and say 'thank you' for his service to his country."
