Speaking about what Tarmey would have thought about his award win, Halsall said: "He'd probably be laughing his head off. He used to say to me, 'None of that bloody acting you!'
"For me to pick up an award for acting, he'd be laughing his head off.
"But his wife, when he passed away, gave me his watch which I'm wearing tonight, so he's with me really."

The soap star claimed that he was genuinely surprised by his victory and said that he was "thrilled" and "humbled" by fans having voted for him.
He also confirmed that he was hoping to match Tarmey's 31-year stretch on the show as Jack Duckworth. "I'd like to emulate Bill and get to 31, but I'm only halfway there!" he said.
