The Health Minister says the government will arrive on a unified position on a bill calling for the repeal of the 8th amendment.
The bill is being put forward by the Anti Austerity Alliance / People Before, with the group's TDs calling for a referendum on the 8th.
The proposal will be debated in the Dáil tomorrow night, ahead of a vote on Thursday.
The cabinet is reported to be at odds over the motion, with the Independent Alliance looking for a free vote on the issue.
Government ministers will discuss the matter at tomorrow morning's cabinet meeting.
Enda Kenny has said the bill would "cut across" the Citizens' Assembly which has already been set up - and that it would conflict with the Programme for Government.
Simon Harris told Limerick's Live 95 any decision will be taken with the assembly in mind.
"An awful lot has happened since the last time this issue was debated in the Dáil," he suggested. "The Citizens' Assembly was in the past a concept - now it's up-and-running."
