An email from notorious prisoner Charles Bronson has been read out at the funeral of Ronnie Biggs in which he paid tribute to the Great Train Robber as "staunch, solid, loyal to the end".
The homage from Bronson continued:
Much respect to a diamond geezer. I do hope the royal family show their respect with a nice train wreath. Three cheers to you Ron, we love you buddy.
Nick Reynolds, the son of the late mastermind of the 1963 robbery Bruce Reynolds, meanwhile described Biggs in heroic terms, saying:
The word legend is defined in the dictionary as an extremely famous or notorious person, especially in a particular field, and Ron certainly fits that description.
Speaking about the ill health Biggs had suffered in his last years, Mr Reynolds said: "The house was a wreck but the lights were on and Ron was very much at home."

Nick Russell-Pavier, author of The Great Train Robbery: Crime of the Century, told ITV News there are "two Ronnie Biggs".
"There is the sort of cartoon character who featured in The Sun and doing videos with the Sex Pistols, and there's the small-time thief who was catapulted into the extraordinary tale," he said.
Author Mike Gray, who has written numerous books on the Great Train Robbery and on Ronnie Biggs, said he was sad to hear of his passing as "he has become part of my life and myself part of his."
Mr Gray, whose books include Ronnie Biggs: The Inside Story, said he visited Biggs every month for eight years while he was held at HMP Norwich and HMP Belmarsh.
He said: "He was never a bad person. His criminal CV was laughable before the train robbery and none of the train robbers wanted him on the robbery as they had never heard of him.
"He was only invited as mastermind Bruce Reynolds was Biggs' best pal and Biggs knew a retired train driver. Biggs always regretted the injury to [train driver] Mr Mills."
Ronnie Biggs and his son Michael were interviewed in August at the memorial of Bruce Reynolds, dubbed the mastermind of the Great Train Robbery.
Michael Biggs told ITV News correspondent Simon Harris his father still had very clear memories of the robbery as he was "blessed with a photographic memory".
Asked how important it was to remember the heist, he said "Crime is always wrong so that should be at the top of everyone's agenda, however it is part of British history now ... that can't be changed."
