Joshua Vaughan and Dawn Steele join EastEnders as Josh and Sandra

How will Zoe react when she comes face-to-face with her long-lost son?

EastEnders has confirmed that Zoe Slater will be in for a shock this month when her long-lost son and Jasmine’s twin brother, Josh, arrives in Walford, having followed his adopted mother Sandra Goodwin to Albert Square.

Sandra turns up seeking answers about Jasmine, unveiling new details from her past and insight into Sandra's version of events. Meanwhile, unbeknownst to Sandra, Josh has followed her to Walford looking for her, not knowing his birth family is closer than he realises.

Dawn Steele will join for a short stint playing Sandra, whilst rising star Joshua Vaughan will join the cast permanently.

With Jasmine’s future hanging in the balance and emotions at an all-time high, their arrival is set to cause repercussions for everyone involved.

On joining the cast, Joshua Vaughan said “It has been incredibly humbling to join the cast of EastEnders and find myself at the intersection of the iconic Trueman and Slater families. Getting to work alongside such legacy actors is a masterclass, and I’ve learned so much from them. Josh is a big ball of love and I’m so excited for the audience to see the drama unfold as he arrives onto the Square.”

To which Dawn Steele added, “I was thrilled to be asked to play the role of Sandra who arrives and throws a spanner or two into the Square! It was so great to go back to Elstree after the end of Holby City. Lots of the same crew (and a few cast!) are still there so it was joyful to see them all again. Everyone was so welcoming and I really enjoyed learning new ways of filming, it really is a well-oiled machine, and everyone works so hard. But it was Sandra’s storyline and character that really made me want to do it and I’m sure viewers will be thrilled with another piece of the puzzle ahead of the trial, Sandra’s timing couldn’t be better, or worse…”

And speaking about today’s news, Executive Producer, Ben Wadey said “I’m thrilled to welcome Dawn Steele and Josh Vaughan to EastEnders as they step into the roles of Sandra and Josh Goodwin. Since her return last year, Zoe has searched for her long‑lost son, and we’re excited to finally add the missing pieces to her story. As always with the Slaters and Truemans, nothing is ever straightforward, and the arrival of Sandra and Josh promises even more drama for Walford at a pivotal moment as Jasmine’s trial begins.”

EastEnders continues Monday to Thursday at 7.30pm on BBC One with first look episodes available from 6am on BBC iPlayer
