Evil businessman Frank Foster, who raped ex-fiancé and business partner Carla (Alison King) in a recent controversial storyline, will meet his end at his Underworld factory in tonight's Weatherfield instalments.
Speaking on This Morning, Lancel explained: "I've always known what this guy was going to do and who he was going to do it to so that's been really helpful because it's always been bookended and final.
"But now it's over and this mega storyline will take over. I didn't know the exact details but if you play a character that goes out with Carla Connor you're going to die - that's the way things seem to go so the clue was there from the beginning.
"When you close one storyline another one opens but the last time you see him alive there will be no doubt as to what kind of a man he is like."
Referring to the murder whodunit, the actor teased: "Sally Webster has given her heart and her life to this man and to say she is feeling slighted is an understatement. She's lost everything to him and he's broken her in two.
"Kevin still loves his wife and is finding out what Frank does to Sally so he has more than one reason to kill him.
"With Carla, he's just wiped her out and destroyed her and she's got more reason than anyone to kill him."
Coronation Street airs tonight at 7.30pm and 8.30pm on ITV1.
