Billy Connolly: Assessed as having the initial symptoms of Parkinson’s disease and is receiving treatment.

Billy Connolly will continue to perform on stage and screen despite undergoing surgery for prostate cancer and being treated for the “initial symptoms” of Parkinson’s disease.

The 70-year-old star started his showbusiness career as a folk singer before developing the stand-up act that made him famous.

His spokeswoman said: “Billy Connolly recently underwent minor surgery in America after being diagnosed with the very early stages of prostate cancer. The operation was a total success, and Billy is fully recovered.
