"On behalf of the Trustees, Governors and staff of Letchworth Garden City Heritage Foundation, we wish to add our condolences to the many thousands of other well deserved tributes to a most remarkable man.
"Young people here and all over the world owe him a huge debt for creating and supporting the Duke of Edinburgh’s Award Scheme, a lasting legacy of which he was very proud.
"A long life, well lived."
