Groups representing survivors of the Magdalene laundries have described Enda Kenny's failure to provide them with a formal apology as "shameful".
A government commissioned report found clear evidence of state involvement in the running of the Magdalene laundries.
But it said physical and sexual abuse and torture were not a feature of the laundries.
Mari Steed from the Justice for Magdalene's group said the failure of the Taoiseach to apologise to the women involved is a disgrace.
Meanwhile, survivors of the laundries are disputing parts of toda'ys report which claim that phyiscal abuse was not a feature of the work houses.
Maureen Sullivan says she was phyiscal abused and beaten during her time at the laundry.
"They boxed you into the head," she said, "especially when I went there first. When my mother came to visit me and I told them I would tell her I'm not going to school, they gave me an awful beating."
