Signatures of presidents and princes in Downing Street visitor books made public for first time Three visitors' books from Downing Street signed by some of the most famous names in modern history have been released to the public for the very first time.
The guest books provide valuable insight into who had private conversations with prime ministers in the past, as the names of visitors to Number 10 are rarely made public.
The remarkable collection of signatures includes numerous world leaders and members of the Royal Family, such as the late Queen, Princess Diana and King Charles III when he was the Prince of Wales.
When the late Queen visited Downing Street she would sign herself Elizabeth R, while the present King and his then wife were simply Charles and Diana.
Signatures also include successive US presidents from Jimmy Carter through Ronald Reagan, George Bush senior and Bill Clinton to George Bush junior.
