His family confirmed that the star, who appeared in seven 007 films, died from “a short but brave battle with cancer” in a statement on Twitter.
They said: “With the heaviest of hearts, we must share the awful news that our father, Sir Roger Moore, passed away today. We are all devastated.”
His children Debora, Geoffrey and Christian added: “Thank you Pops for being you, and being so very special to so many people.”
They revealed that Moore died in Switzerland and will be buried in Monaco, after a private ceremony.
“The love with which he was surrounded in his final days was so great it cannot be quantified in words alone,” they continued.
“Our thoughts must now turn to supporting Kristina [his wife] at this difficult time.”
Moore’s performance as Bond in films like Live and Let Die (1973) and The Spy Who Loved Me (1977), is considered one of the most iconic of the franchise.
