The Scottish Socialist Party called on the Scottish Executive to make a statement on the use of Greenock Prison to hold asylum seekers.
SSP justice spokesman Colin Fox said Justice Minister Cathy Jamieson should address the Scottish Parliament as "a matter of urgency".
He said: "The use of Scottish jails to hold asylum seekers who have committed no offence and who have not been charged with any crime is an extremely serious development.
"The executive can no longer remain silent when its ministers are now directly involved in the way that asylum seekers are being treated in Scotland."

Glasgow MSP Rosie Kane returned to the proceedings after a break, and strapped herself to two teenage girls using homemade submarine-shaped tubing. Police moved in and Ms Kane and the girls were carried off by four officers. The MSP was charged with the same offences as her colleagues. She said: "I’m sick of our taxpayers’ money being spent on the arms race when housing, schools and public services in Scotland are in dire need of funding, and it’s time the electorate gave the politicians a kick in the ballot box."
