I don’t rule out Simon either, Tina has split his family 
I think it’s Roy, the strain of losing Haley being too much to bare, and seeing Anna holding a secret that is destroying her, he mistakenly thinks Tina has had a Lesbian affair with Anna, he is pushed over the edge to act for justice as he sees it.
Or it could simply be someone who happened to be ‘up there’, wherever she falls from, a builder maybe, who inadvertently stuck out his elbow and caught her a glancing blow which toppled her over the edge. He is shown peering down at his fatal error, going ‘…oops! 
’
Ooh, I know, sticks hand in air. Please, miss! I think it’s Tony. Michelle finds out about his criminal activities with Tracey Luv and threatens to dob them in.
Or it’s Lloyd. So they can continue with their MLI game, as coined by Jaci Stephen in the Daily Mail…Make Lloyd Interesting! A complete failure, every time.
No, it’s Charity and Declan. They supposedly go on their Barbados honeymoon but they actually make their way to Weatherfield to kill off the competition, so they can win next year’s Villains of the Year Soap Award.
Blimey, I know bar staff are hard to find, but would you murder someone just for taking too many breaks?
Oh I’ve just read on another forum that Peter wants a break from Corrie for a while! Could be him then.
No, she only gave her a few seconds notice that she was leaving. Right there and then! :-D. Nobody in tv land ever works through their month, or week: they always leave that episode. Well that’s what happens on Holby and Casualty.
Oh so now we know who did the dirty deed on Corrie.
will Ken return? He looked quite frail at the Soap awards recently
I hope he does return Honey.
me too!
Phew! No long drawn out whodunnit, thank goodness! I was beginning to point the finger at Roy! Would he be a reliable witness, do you think!
I thought we wasn’t going to see how she came to fall and would be left guessing who she was with
All hail Rob, that’s what I say! I couldn’t stand Tina and what she was doing with Peter, although in fairness he wasn’t blameless.
I’m confused - I thought there was going to be a long drawn out whodunnit thing going on, so how come we know it was Rob?
They’ve probably listened to the viewers in the past. It might mean though that the Weatherfield police will take a long time getting results, or that Rob might get away with it.
Just so long as WE know. 
I reckon that at first they will think it was suicide because of her being so upset over Peter.
I quite liked Tina, thers a few that I wouldnt mind going
over a wall tho…lol 
Tina had been round the block a bit, David, Tommy, Matt, Jason, Peter, but she finally Fell for Rob.
Well, they said there would be a shocking twist!
