EastEnders is reportedly planning a storyline involving the tragic death of a newborn baby in the New Year.
The Daily Star Sunday claims that producers are refusing to reveal whether the plot will involve Kat Moon or Ronnie Mitchell.
A source said: "The baby will be born in the New Year but will sadly die from a rare condition just a few days later. It's going to be heartbreaking. The doctors aren't able to do anything to save the tiny baby and there will be a lot of unanswered questions surrounding his death."
Ann Chalmers, chief executive of Child Bereavement, said: "The death of a child is a particularly difficult and painful kind of loss. Anyone who suffers such a loss will need the appropriate support, which I hope EastEnders will show."
A spokeswoman for the soap added: "Everyone knows Kat and Ronnie are both pregnant so it doesn't take much to work out when they may both be due. But it is way too early to confirm storylines as it will only spoil things for viewers."
