Clare Labour TD Michael McNamara is to introduce a bill in the Dáil tomorrow to allow for the termination of pregnancies in cases involving fatal foetal abnormalities.
Mr McNamara said the bill includes a definition of fatal foetal abnormalities and sets out the medical conditions where it would apply.
This would involve cases where the baby would not be born alive and also cases where the baby would be born without a brain and would die a short period after birth.
The mother would have the choice to have a termination, he said.
His bill comes a few days after the party's conference during which an internal committee involving Senator Ivana Bacik recommended a referendum should be held to deal with a broad range of issues including fatal foetal abnormalities, incest, rape and a risk to the mother's health and life.
It consulted legal and medical experts.
The party also reiterated that a referendum should be held to repeal the eighth amendment.
Mr McNamara said he supported the party's position but he added the onus was to legislate for the current situation.
Labour rejected independent socialist Clare Daly's bill on numerous occasions as it believed it was unconstitutional.
Mr McNamara said his bill was more restrictive.
Fine Gael has not agreed to go further than the Protection of Life during Pregnancy legislation, which dealt with the X case.
Meanwhile, the Labour Party has decided to include Willie Penrose's bill on bankruptcy in the upcoming review on insolvency legislation.
Mr Penrose's bill provides for the bankruptcy period to be reduced from three years to one year.
The party endorsed the bill at a meeting this evening.
Fine Gael has not stated a position on the bill and is unlikely to do so until it is selected for second stage in the Dáil.
