River City actor Johnny Beattie, who lives in Glasgow, has added his name to a parent-led campaign to prevent Glasgow City Council shutting St Oswald's Secondary, an Additional Support for Learning (ASL) school in Cathcart, and move the pupils into classrooms at St Margaret Mary's Secondary in Castlemilk.
A group of concerned parents have opposed the move and are campaigning to retain the current school.
They are concerned that the children will not cope with a mainstream environment.
The comedian and actor, who has more than 50 years show business experience behind him, has a family member at the school.
He has submitted a letter to James Dornan, the SNP MSP for Glasgow Cathcart who is backing the campaign to retain the school at the current site.
Mr Dornan said he had no concerns over shared campuses, but was worried about forcing an ASL school into a mainstream school and the upheaval it could cause for children.
Mr Beattie's great niece is a pupil at the school and he said she has been very happy there.
Mr Beattie said: "The idea of a move is very upsetting for the children and their parents. It's important that the interests of the children are considered."
The consultation on the proposed move closes next week, when a decision will then be taken.
