Billy Connolly has confirmed his stand-up days are over, following his diagnosis with Parkinson's in 2013, but insisted he will not let the disease ''define him''.

The 77-year-old comedian, who was diagnosed with the disease in 2013 , has now insisted his days on stage are over.

Speaking to Sky News, Connolly said: ''I'm finished with stand-up - it was lovely and it was lovely being good at it. It was the first thing I was ever good at.''

Connolly is invited to numerous engagements with other Parkinson's sufferers, but admitted he turns a lot down because he doesn't think it would be ''particularly good'' to let the disease ''define'' him.

''I'm always being asked to go to Parkinson's things and spend time with Parkinson's people, having lunch or something like that. And I don't approve of it.

''I don't think you should let Parkinson's define you and all your pals be Parkinson's people."

''I don't think it's particularly good for you. So I don't do it.''

The comedian admits he gets ''upset'' over his diagnosis, and admitted it means he walks ''like a drunk man'' at times, and it can limit him from doing certain things, such as putting change back in his wallet.

He added: ''Certain things go wrong, your brain goes adrift and affects your body, and so you walk differently, you walk like a drunk man sometimes.

"And you're frightened you'll be judged on it. And you shake sometimes.''

In October, Connolly gave fans an update on his Parkinson's disease and said he is "taking my medication and getting along with it".
