Coronation Street producer Stuart Blackburn has revealed this summer’s big storylines that will see the return of Ken Barlow, Peter Barlow (Chris Gascoyne) being charged with Tina’s murder and meeting up with Jim McDonald (Charles Lawson) in prison, plus troubled Kylie Platt resorting to taking son Max’s ADHD medication.

On the Tina murder storyline, Stuart says: “Rob will do everything he can to point the finger of guilt at Peter. It looks like it might work. We’re going to see Peter arrested and see him on remand. We’ve built a massive prison set and it will also see the return of Jim McDonald who, as we know, is in prison [for armed robbery in 2011].”

William Roache, who plays Ken Barlow, will be returning after being cleared of sexual assault charges in February.

“Ken’s coming back to quite a few surprises,” Stuart continues. “Deirdre hasn’t told him the extent of Peter’s problems and, actually, what we will see with Ken is that he will be the one person who Peter can turn to.”

There’s torment ahead for the Platt family, too… “Over the coming weeks, we see a real change in Max’s behaviour and what we are going to learn is that he is suffering from ADHD,” Stuart reveals.

“We have done an awful lot of research on this and it’s going to take us to a point where Max is going to be put on medication. Kylie hits a really low point physically and emotionally. She’s completely drained and she takes some of Max’s medication.

“She’s utterly ashamed and David is disgusted when he finds out. This is, out of all the bad decisions Kylie has made, the worst one ever. It’s going to have a devastating effect on her, her health and those around her and it’s going to bring real trouble to the door of the Platt household.”

And Paula Lane, who plays Kylie, confirmed she’s going to have a busy summer filming, tweeting, “Another early start for moi, it looks like I’m going to be a permanent member of the 6am brekkie club for the summer!”

Stuart, who was talking on the Coronation Street website, also revealed that Tyrone’s life is going to be turned upside-down again, this time by Jason’s dad, Tony.

“Just when we think Fiz and Tyrone have finally got some happiness and are looking to the future, disaster is going to strike and this is going to put Fiz and Tyrone up against the Grimshaws,” says Stuart. “Right at the heart of that is Tony and we are really going to see his true side – or one of his sides.”

And Stuart promises that the soap’s dramas will continue to build in the autumn and winter months.

“We’ve got much more coming up as we head towards Christmas – plus some great comedy with Beth, Kirk, Sinead and Chesney,” Stuart says. “And watch out for the Windasses as they’re going to be back in action soon. All round there will be that mix of great drama, romance with Gail and Michael, new characters and – always at the heart – great comedy.”
