Venn has played the role of Ray Dixon in the BBC One serial since January 2012, when Ray came to Walford to track down his son Morgan (Devon Higgs).
Bosses have now taken the decision to write the character out.
Venn told Digital Spy: “Working on EastEnders has been one of my career highlights and an invaluable experience.
“I couldn’t have asked for a better team to work with and have found a life-long friend in my on-screen partner Tameka. I want to thank everyone who
supported me on the show.”
Ray is expected to leave the soap in June when he moves closer to his daughter Sasha as her mother is unwell.
An EastEnders source told Inside Soap: “The door will be left open for Ray. Chucky has been a great cast member and a pleasure to work with.
“Ray’s always going to be connected to Walford while Morgan is there – and who knows, he may pay his little lad a visit one day in the future.”
