“The Duke of Edinburgh’s awards did so much for young people - and of course we should not forget his record in the Mediterranean and the Pacific during the Second World War.
“His devotion to the Queen and his service to the country was unparalleled.”
A borough e-book of condolence has been set up online for people to sign and leave messages.
The virtual book will be available until the day after the funeral, the arrangements for which will be announced in due course.
