An inside source told The Sun: “Derek gets drunk and starts waving a gun around the pub.
“There’s a tense stand-off then a massive fight between the two men and two people are shot, including Robert, who dies on Christmas Day.
“He makes it to hospital but suffers a heart attack and dies off-screen in a bit of snub to Tristan. It’s left to Michelle to tell everyone he’s dead.”
Tristan is among a flurry of favourites leaving the soap as his on-screen partner Michelle Connor (Kym Marsh) is also on the way out.
But without Michelle being killed off, could we see the brunette bombshell return to the cobbles in the future?
