Comedian Ross Noble has attacked BBC comedy panel show Mock The Week, saying it's "terrible".
Noble, who often appears on quiz show Have I Got News For You, told the Radio Times that the comedians on Mock The Week allegedly don't have to improvise.
When asked why he had never taken part in Mock The Week, Noble said: "Because it's terrible. If you watch Mock The Week, watch when the camera goes wide, look at the scripts - they've got pages and pages of them.
"You watch Have I Got News For You and they show a wide shot, there are no notes there. You watch Mock The Week, there are A4 pages spread out if you look at the desk in front of them."
He continued: "When you see spin the wheel, what subject could be coming up now and you do a little bit of stand-up about it - it's really weird that when the wheel spins, the topics that come up usually relate to something that is in that person's act.
"I've not been on that show but they clearly get them in advance."
The 37-year-old from Newcastle is currently hosting his travel documentary series Freewheeling on Dave.
