Lucinda Creighton has lost the Fine Gael party whip after voting against the Government in the abortion debate tonight.
The Dublin South-East TD will also be removed from her position as Minister of State for European Affairs.
Creighton, who has fiercely opposed the suicidal element in the legislation, voted against the Government in support of an amendment to remove the clause that was proposed by fellow party rebel Billy Timmins.
Speaking shortly after her self-imposed exile, Ms Creighton confirmed she will resign from her post within the Department of the Taoiseach.
She said she was very sad to forfeit her job and lose her position in the Fine Gael parliamentary party, but she knew the consequences when she cast her vote.
“I hold no rancour or bitterness or anything like that,” Ms Creighton said.
“I’m very sad, but I genuinely wish Enda Kenny and all the Government the very best.”
Ms Creighton, who has been a member of Fine Gael since she was 18, spoke to the Taoiseach after her rebellion.
She said she still has “huge admiration” for him.
“I’m very sad. I love my job. I’ve been very privileged to perform my functions and duties as minister for European affairs for the last two years and more, and it’s very sad for me that that is over. But I knew the consequences when I voted,” Ms Creighton added.
