EastEnders star "in tears" over exit
In an interview with TV Times, Partridge, who plays Christian Clarke, was asked if making the decision to leave was difficult.
He replied: "Leaving was incredibly emotional, and the last day was very difficult. You have the whole anticipation of it coming and, when it finally happens, it's overwhelming.
"I was in tears; our executive producer, Lorraine Newman, was in tears; the people in props were in tears. Afterwards, I felt exhausted."
Asked whether he made his decision aware that Marc Elliott, who plays Christian's partner Syed Masood, was also leaving, Partridge replied: "Christian and Syed are a unit. I know some characters can survive having their other half leave but, for me personally, I didn't see a future for Christian without Syed.
"It was very much a joint decision and it wasn't an easy one for me to make but, at the same time, you have to serve the story and there has to be a professional happiness tied into that. In reality, I think I would've been slightly redundant without Marc."
"I have had the most amazing time, and it's one of those jobs that I will hold dear," Partridge concluded. "My memories will be kept in my heart - and I mean that most sincerely."
