Later this year, viewers will see Ben get released from juvenile detention after six months locked away - and it's not long until he's at the centre of more family drama on Albert Square.
As he tries to readjust to life in the outside world, Ben becomes caught in the middle as his release reignites old animosities between his dad Phil (Steve McFadden) and half-brother Ian (Adam Woodyatt).
Meanwhile, Shirley Carter (Linda Henry) and Jane Beale (Laurie Brett) are also on hand to support the youngster as he settles back into his everyday life.
Joshua Pascoe as Ben Mitchell
Speaking of his casting, Pascoe commented: "I was so excited when I got the call to say I'd got the part of Ben Mitchell. I never thought I'd get on to a show as big as EastEnders.
"I've always watched the programme and it will be great to work with fantastic actors such as Steve McFadden and Linda Henry. I'm really looking forward to this fantastic opportunity and making the role of Ben my own."
Pascoe takes over the part from Charlie Jones, who made his final EastEnders appearance earlier this year.
