Tina Carter's (Luisa Bradshaw-White) former girlfriend Tosh is to arrive in Albert Square this February on a mission to win back her ex.
It will soon become apparent that there is no love lost between firefighter Tosh (Rebecca Scroggs) and Tina's sister Shirley (Linda Henry), but show bosses have described the newcomer as "strong, feisty and bright", suggesting that Shirl may not be getting things all her own way.
Viewers will see Tosh making her mark as "a fierce grudge bearer" - the key message being: cross her and you'll know about it.
On her new role, Rebecca Scroggs (who had a guest role in the first series of crime drama Death of Paradise) said: “I’m very excited to be joining EastEnders in my first major television role. I grew up watching the show and it feels amazing to actually be a part of it now! I’m really going to enjoy working with the Carter family, they've brought such great energy to the Square.”
