On Peter and Carla's future, he commented: "When I took over, they'd come back from America - but I kept reading weeks of scripts where they didn't have much to do. I wanted to address that as soon as we could.
"We see Peter and Carla as being like Richard Burton and Elizabeth Taylor. They'll make it to the altar later this year, that I can say. But whether they end up together for life or not, I don't think there is a damn thing either could do to the other that would fundamentally stop them loving each other! It's just that love isn't always enough."
Blackburn also revealed which characters will be taking centre stage at Christmas this year.
Asked how he will make sure Coronation Street beats EastEnders in the festive ratings battle, he replied: "Simply by having fantastic drama. It's Hayley's last ever Christmas, but her best ever. Gail will try to get the Platts and Prices to heal old rifts, and it'll be explosive for Carla, Peter and Tina as well."
