Actor Iain Robertson has accused the National Theatre of Scotland of blacklisting performers.
The Scottish, BAFTA-winning actor claimed he is among performers who have been barred from performing in plays by the NTS.
Writing on Twitter, he claimed he has not had a “single availability check” in “13 odd years”.
He also tweeted: “A former employee who worked in the casting department told me to my face that there was a blacklist and that I was on it.”
A spokeswoman from the National Theatre of Scotland denied the claims, and said the organisation “does not operate any kind of ‘black list’ or indeed ‘preferred list’ of actors that would inform the casting processes/decisions made by the company.”
“The National Theatre of Scotland is committed to an inclusive and diverse casting policy and practice,” she added.
Robertson called on Equity to show its support.
He added: “I’m speaking up for the countless actors in Scotland for whom a gig from @NTSonline means the difference between paying the mortgage or throwing themselves at the mercy of Universal Credit.”
Robertson has said he plans to attend Equity’s annual general meeting to encourage “transparency from the public body” and to establish if the blacklist exists.
Equity declined to comment.
