Two prominent politicians at Holyrood and Westminster have urged both chambers to debate the future of the Borderline theatre company.
The theatre faces closure after losing its core funding
Justice Minister Cathy Jamieson and Des Browne, Chief Secretary to the Treasury, want to reverse the decision to cut the theatre's £215,000 funding.
The Scottish Arts Council withdrew funding amid concerns over the quality of work by the Ayrshire-based group.
A cross-party group of MSPs and MPs has been fighting to save it from closure.
Borderline, which has showcased the talents of actors including Billy Connolly and Robbie Coltrane over the past 30 years, has finance for three more productions.
Ms Jamieson and Mr Browne have been seeking a member's debate and an adjournment debate on the issue at Holyrood and Westminster respectively.
A group of nine politicians, including Labour MPs Brian Donohoe, Katy Clark, and SNP MSP Adam Ingram, met Borderline producer Eddie Jackson last week.
In a joint statement, the group said: "We are all supportive of Borderline and its campaign.
"We will endeavour to secure a member's debate at Holyrood and an adjournment debate at Westminster to highlight the need for Borderline to continue with core Scottish Arts Council funding."
Mr Jackson said he was heartened by the level of local political support.
"We already have the support of artists like Gregor Fisher and Elaine C Smith and writer John Byrne," he said.
"Getting the backing and help of this cross-party group of politicians has given us a major boost, which will hopefully help us persuade the Scottish Arts Council that we deserve to continue."
The SAC said it wanted to concentrate on stronger organisations when it announced its funding plans.
