"What an honour it was to work with Duggie. A born entertainer who loved his profession. RIP Duggie Brown. We love and salute you."
Fellow comedian Tommy Cannon shared a tribute to the star online, tweeting, "Really sad to hear about the passing of Duggie Brown, Rest in peace pal, what a funny funny man- thinking of all your friends and family."
Actor Neil Hurst wrote, "Beyond sad to hear that my ol' pal Duggie Brown has passed away.
"One of my very first telly jobs was with Duggie back in 1997 and I was lucky to appear in so many shows with him since. Genuinely one of the nicest and funniest guys in the business."
"I'm very sad to hear Duggie Brown has left us," wrote Russell Grant.
"I shared many a breakfast sofa with him. His appearances on stage, in tv drama and light entertainment was prolific.
"A warm, modest, down-to-earth man. I was completely bowled over how he could turn his talents from stand-up to acting."
