Arts organisations in her area are in need of more financial support, says Jane Dodds.
The Mid and West Wales MS said at the Senedd that organisations such as The Hafren, Mid Wales Opera and Impelo have lost their funding completely.
She said the Wyeside Arts Centre, which she said is an iconic venue in Builth Wells that has served the people of Powys for decades, has had its support cut to “a mere 20 per cent”.
Ms Dodds told Government Business Minister, Lesley Griffiths: “Sadly, if it doesn't get any funding by 2024, the curtains could come down for good.
“Whilst I understand the allocation of funding is done by the independent Arts Council of Wales, I wonder if consideration might be given to interim funding to tide them over until the outcome of an appeal.”
Ms Griffiths said the Welsh Government funds the arts mainly through the Arts Council of Wales, which operates in accordance with an “arm's-length principle”.
She said it is important for organisations that have lost funding to have had the opportunity to engage with the appeal process.
Ms Griffiths said: “Wyeside Arts Centre had been successful.
“It hasn’t received the full amount, and unfortunately many successful organisations, with the current financial position, did not receive indicative awards for the full amounts requested through the investment review.
“The outcomes of that review are a matter for the Arts Council for Wales.”
