The best Corrie characters we've never seen

With Harry the bookie making reference to his third ex-wife Francesca, she sounds a force to be reckoned with. And it's got me wondering if we'll ever see her on screen, and indeed if we ever should.

She could go down in history as one of the best Coronation Street characters that we've never seen, along with the wonderful Yana Lumb's very own fella, Big H, and the often referred to but never seen taxi controller, Fat Brenda from Levenshulme.
