London: Actor Robert Vaughn, best known as the secret agent Napoleon Solo in 1964 TV hit series "The Man from UNCLE", has died after a battle with acute leukaemia aged 83, media reports said.
Vaughn died in New York on Friday morning surrounded by his family, his manager, Matthew Sullivan told the BBC.
Vaughn, who was "a few months shy of 84" had been seeking treatment for his leukaemia, Sullivan added.
Vaughn was also famous for his role as Lee in the "Magnificent Seven", and television roles in "Hustle" and "Coronation Street".
David McCallum, who starred alongside Vaughn in "The Man From UNCLE", said he was "utterly devastated" by the news.
"Robert and I worked together for many years and losing him is like losing a part of me. My deepest sympathies go out to Linda and the Vaughn family," he said.
Other notable films of Vaughn include "Bullitt" and "Towering Inferno", both with Steve McQueen, and was the villain in "Superman III".
The actor is survived by wife Linda, son Cassidy, 40, and daughter Caitlin, 35.
