The Taoiseach says new tracing legislation for those affected by illegal adoption will be advanced as a priority.
His comments come after an RTÉ Investigates revealed thousands of Irish babies were illegally adopted over several decades, with many unaware they had been adopted or that it was illegal.
Micheal Martin told his parliamentary party last night the issue is shocking, and goverment will work to ensure those affected are helped and supported.
Founder of adoptee rights group, Aitheantas, Maree Ryan-O'Brien, says this needs to happen right away
"Somebody discovering late in life that they have been adopted albeit illegally that has profound mental health affects.
"If anything we've become more aware and appreciated even more the necessity for people to talk, and to have mental health supports available."
