The Duke of Edinburgh "was involved in every detail" of the planning for his funeral, the Archbishop of Canterbury has told Sky News.
The Most Rev Justin Welby said Saturday’s order of service has been in the planning for more than 25 years.
"He was more than involved in the planning of it – he was involved in every detail of it," Mr Welby told Dermot Murnaghan.
"It’s been meticulously planned over a quarter of a century and when the order of service is seen, his imprint will be all over it.
"He didn’t want a fuss and he knew exactly what he wanted in it.
"It is thoughtful and I think people listening to the service, watching it on TV will find it speaks very deeply to their own hearts."
Prince Philip‘s funeral will be attended by just 30 guests due to coronavirus restrictions, and social distancing rules mean the Queen will sit alone.
Mr Welby will give a blessing during the service at St George’s Chapel in Windsor.
The Duke of Edinburgh will be interred in the royal vault in the chapel at the end of the service, which will be conducted by the Dean of Windsor, David Conner.
And Mr Welby said he "never fails to be admiring of how Her Majesty behaves".
"It’s been one of the greatest privileges of this role to get to know her a little bit.
"She will be sitting on her own and masked but it will never cross her mind to complain about that.
"She will reflect and will show her normal dignity and composure."
