The Senate lion, who’ll always be my Senator even when he’s dead and gone, joins a shortlist of Americans that have been awarded honorary Knighthood by Queen Elizabeth II.
Kennedy joins Bill Gates, Rudolph Guiliani, George Bush Senior and Stephen Spielberg.
In his address Mr Brown said: “I hope that you will allow me to single out for special mention today one of your most distinguished senators, known in every continent and a great friend.
“Northern Ireland is today at peace, more Americans have health care, more children around the world are going to school and for all those things we owe a great debt to the life and courage of Senator Edward Kennedy.
“And so today, having talked to him last night, I want to announce that Her Majesty the Queen has awarded an honorary knighthood for Sir Edward Kennedy.”
