Labour has demanded to know if the temporary ban on the transfer of violent transgender prisoners will be made permanent.
Two of the party's MSPs have written to SNP justice secretary Keith Brown to ask why it took so long for the government to intervene over the transfers of Isla Bryson and Tiffany Scott.
Pauline McNeill and Katy Clark have also called for the Scottish Parliament's justice committee to be provided with information on the pattern of offending among transgender prisoners held in women's jails.
