A source told the Daily Star: “It’s touch and go whether Kat survives. She wasn’t meant to be in the house on the night it goes up in flames.

“Stacey, Alfie, Big Mo, Lily, Tommy, Bert and Ernie all live in the house and the fire will involved other Walford residents as well, so it remains to be seen if she is the only victim.”

Jessie Wallace, 42, who plays Kat, is already being tipped to win awards for her performance and portrayal of this very sensitive subject.

The source continued: “Her injuries are physical. She is badly burned and this will affect her for the rest of her life.

“Jessie will undergo special effects make-up so her injuries look as realistic as possible. There’s also the emotional side of what she’s going through.
