Australian comedian Barry Humphries, famous for his character Dame Edna Everage, has been ordered by doctors to rest for six months.
The 73-year-old star has reportedly been forced to cancel a number of shows and appearances due to complications following appendix surgery.
A spokesman for the Glasgow International Comedy Festival said: "He's going in for surgery this week as there have been complications."
The spokesman continued: "He has been told by his doctors to take a six-month rest."
