Fianna Fáil's Dara Calleary says there are "divisions" in the party on abortion policy, but the party remains "very pro-life".
The party is refusing to say where it stands on legislation to provide for abortion on the grounds of suicide.
Ahead of Fianna Fail's 74th Ard Fheis, Mr Calleary said the party is waiting for the Government to publish its legislation before giving its views.
"Yes, there is, there is different views on it," he said.
The party's jobs spokesman said he favours legislation, but didn't say what this law should entail.
"I'll wait until I see the proposals and I am not commenting beyond that," he said.
At the Ard Fheis, a series of pro-life motions will be debated.
But there were no pro-choice motions put forward by the party grassroots.
"The party is very pro-life," he added.
Fianna Fail's Ard Fheis takes place this weekend in the RDS in Dublin, with 4,000 delegates expected to attend.
