A theatre in Somerset said it may have to close before the end of the year because it is struggling to attract enough funding from the Arts Council.
The Brewhouse Theatre in Taunton said that despite receiving over £150,000 in council grants it needs more money to be able to attract arts projects.
Taunton Deane MP Jeremy Browne has written to the government and the Arts Council about the theatre's problems.
He said he wanted to make sure Somerset was getting a fair deal.
Mr Browne said: "I've written to the Arts Council and the Department for Culture, Media and Sport to say 'can we look at whether Somerset is getting a fair funding deal for the theatre?'
"There seems to be some evidence that other counties in the south west are getting more funding per head of population than we are.
"The Brewhouse Theatre's costs are going up at the same time as the revenues are going up and there is a shortfall.
"The problem they face is that you can't go year after year not covering your costs."
