More Fine Gael TDs could today join the revolt and say they will vote against the Government's abortion laws.
It's the final day of debate on the Protection of Life During Pregnancy Bill ahead of the first vote which is expected tomorrow evening.
The Irish Times reports that 4 Fine Gael deputies have vowed to lose the party whip and vote against the legislation.
Peter Matthews, Brian Walsh and Billy Timmins have been joined by Dublin North East TD Terence Flanagan in saying they cannot support the legislation, especially with the inclusion of the suicide provision.
Today the Dáil will sit for 8 more hours for a second stage debate and more Fine Gael TDs are expected to outline their position.
Other TDs like Junior Minister Lucinda Creighton and Mayo's John O'Mahony may support the Bill in tomorrow's vote in the hope of making changes to it at committee stage.
At this stage though the biggest revolt in government in decades is expected on this legislation.
