The Catholic Archbishop of Dublin says he wants to see all mother-and-baby homes investigated by an independent commission of inquiry with full judicial powers.
Diarmuid Martin's comments, broadcast on RTÉ yesterday, come after reports that up to 800 infants and children are buried in a mass grave in the grounds of a convent run by the Bon Secours order of nuns in Tuam, Co Galway.
He also wants the adoption issue to be looked at.
A number of vigils will take place this week as a mark of respect for the women and children who died at the Tuam home.
Hilary Minch, a spokesperson for Justice For The Tuam Babies, which is organising the gathering, said: "We have been shocked and horrified about the news of what happened in Tuam and rather than sit around silently being angry we want to go out and do something.
"So next Wednesday, June 11, we're going to meet at the Department of Children in Mespil Road and walk from there to the gates of Dáil Éireann on Merrion Square."
