“fat poof” after first meeting the Krays while in Shepton Mallet Prison.
Shortly after the incident Cornell was seen walking down Whitechapel Road shouting: “Where’s that fat w*nker?’ referring to Ronnie Kray.
Ronnie Kray showed up at the Blind Beggar pub where Cornell was drinking, and shot Cornell through the head at close range.
In March 1966 a gun battle took place in a club called Mr Smiths in Rushey Green with the Richardson gang going there intent on wiping out the Krays.
There was only one member of the Kray gang present, Dickie Hart, who was shot dead.
Frankie Fraser, a good friend of the Richardsons, was shot in the hip and Eddie Richardson was shot in the backside.
They were taken to hospital and on their release they were charged with affray and sentenced to five years in prison.
Frankie Fraser was also charged with the murder of Hart but was found not guilty.
Other notable characters in the Richardson gang included the notorious hit man Jimmy Moody, Roy Hall, who operated the electric generator, Albert Longman and Tommy Clark.
Moody was an enforcer for the Richardsons, but also carried out freelance work for the Krays and became one of the most feared criminals to emerge from the London underworld.
A further member of the gang, Harry Beard, was known for frequently urinating on a collector of protection money, who was twice warned by the Richardsons after he pocketed their money.
Another infamous killing at the time was that of Jack “The Hat” McVitie, a minor member of the Krays’ gang, who was killed by Reggie in a move that eventually led to their convictions.
