Queen Elizabeth also conferred honorary titles Commander of the Most Excellent Order of the British Empire on the city's police and fire commissioners for their service after the leveling of the World Trade Center.
Giuliani does not get the right to call himself "Sir Rudolph," but he can put the initials "K.B.E." after his name, according to the British Consulate General. When he was asked if he would like to be called "Sir Rudolph" anyway, the mayor said, "Just call me Rudy. I always like that."
Police Commissioner Bernard Kerik and Fire Commissioner Thomas Von Essen can use the initials "C.B.E."
The titles were announced by the queen's son, Prince Andrew, the Duke of York, during a visit to City Hall. They are to be conferred in person by the queen at Buckingham Palace and the mayor, who rarely leaves New York, was asked if he would go to London.
"I may make an exception," he said.
He said he was "humbled" by the honor and accepted it as "being given to all the people of New York City."
British Ambassador Sir Christopher Meyer read a statement from British Prime Minister Tony Blair, who said Giuliani "provided heroic leadership of the City of New York in the aftermath of the terrorist attacks on the World Trade Center."
"To those in the U.K. who had friends and families in New York and who watched events with intense anxiety, Mayor Giuliani provided reassurance that everything, absolutely everything, was being done to mobilize the city's resources to deal with the tragedy," Blair said.
"Through Commissioner Kerik and Commissioner Von Essen I would like to convey our thanks to all of the New York Police Department and the New York Fire Department for their extraordinary bravery on 11 September and in the days afterwards," Blair added.
Kerik was honored for "remarkable dedication and professionalism in assisting the relatives of British victims." Von Essen was cited for "remarkable dedication and professionalism in attempting to save the lives of British nationals."
Others who have been named honorary Knight Commanders include former presidents George Bush and Ronald Reagan, Secretary of State Colin Powell and Bob Hope.
