Armitage made his debut on the Corrie cobbles in 1984 for a brief six month stint. He returned for two years in 1995 and again from 2006 to 2011
He also enjoyed TV roles in Holby City, Hearts and Minds, Jack the Ripper and children's show Magic Grandad.
Fans will also remember him from a 1983 Yellow Pages advert in which he plays a father trying to convince his son against a racing bike for his birthday, in which he says: "I were right about that saddle though."
The Yorkshire-born star was diagnosed with bowel cancer in 2013. The following year he opened up about his battle with the disease as well as his hopes of returning to Corrie.
Speaking to the Daily Mirror in 2014 he said: “I first noticed a problem last May when I was down in Perpignan in France for my cousin’s 80th birthday party. I noticed a little bleeding in a bowel movement, so when I got home about ten days later I went to my doctor.
“They say smoking and bad diet could have links to bowel cancer, but I’m normally a fit and healthy sort of bloke.”
He continued: “It's 30 years since I first started on the cobbles and I’ve always come in and out. I’d like to go back again if there’s a storyline for me.”
He is survived by his two children Danny and Sally.
