Marc Elliott and John Partridge are to leave EastEnders, it has been announced.
The duo, who play lovers Syed Masood and Christian Clarke, will be written out of the BBC soap in November in a dramatic storyline currently being kept under wraps, reports The Mirror.
Executive producer Lorraine Newman explained: "Marc and John have been a fantastic part of the show and their characters have been a huge success.
"Their storylines have broken boundaries that have not been seen in a soap before and the love for them by the viewers can be seen in their 'Chryed' fans.
"When Marc announced he had decided to move on, we had a tough decision to make. After numerous conversations, which included John, it was decided that there is only one outcome for Syed and Christian.
"We wish them both all the best for the future."
Elliott, who joined the series in 2009, said: "I have had a brilliant time on EastEnders and made some amazing friends. I have also been blessed with some incredible storylines.
"I am especially pleased that the show has tackled and raised awareness of the sensitive subject of being a gay Muslim."
He went on to say: "As an actor you are always looking for new challenges and I feel now is the right time to explore different projects - perhaps returning to my roots in theatre."
Partridge, who first appeared as Christian in 2008, added: "I have had the time of my life at EastEnders, but I have always gone with my instincts - and leaving at the same time as Marc felt like the only thing to do.
"It is the right end to the story and for Christian. But, excitingly, it is also the start of a whole new chapter for me."
Earlier this week, Masood Ahmed actor Nitin Ganatra teased that Syed would return to the "dodgy dealings" of his younger days in a future storyline.
Meanwhile, EastEnders newcomer Gary Lucy's character Danny Pennant is rumoured to be involved in a love triangle with Syed and Christian when he arrives in Walford.
