Sinn Féin TD Peadar Tóibín resigned from the party for his opposition to abortion and says he will now seek to build a new party among the people who voted against the referendum on abortion.
Mr Toibin was suspended by the parliamentary party because of his opposition both to the referendum that abolished the eighth amendment to the Constitution and to the legislation currently being passed through the Oireachtas.
However, his announcement marks a complete break with the party after 21 years. Following is Offaly TD Carol Nolan, who has also left the party to oppose abortion.
While Fianna Fáil and Fine Gael exercise a conscientious vote on abortion, Sinn Féin insists his TDs observe the party party for the issue.
In a letter to party leader Aengus Ó Snodaigh on Thursday, Meath West TD said he resigned the party immediately "with a heavy heart."
He said he was excluded from the rights by speaking, the positions of the representative and had "censored significantly" in his media appearances.
He said that he had "tried to know how to make space with the party for people with different views on this subject", but they were always disappointed and missing.
It is with a heavy heart that I leave today from Sinn Féin. I have been a member of the party for 21 years. At that time, I made all my efforts to achieve Irish unity and economic justice. That clearly is no longer enough. I will now help build a new 32-county movement. pic.twitter.com/RqzimdR8Zp

Mr Tóibín, who was ratified for the first time by his party after his opposition to the bill on the protection of life during his pregnancy in 2013, complained that he had a "written agreement" with the party since 2012, "he said that the party would also include me marginalizing myself because of my views on the right to life, as much as I gave the party's opinion. "
He said: "This deal worked well for four years at no cost to the party. More than 18 months ago, this agreement was unilaterally conducted by the party."
Mr Tóibin said he wrote to the party leadership two weeks ago "to know that there was a future for me and republicans like me to contribute to the development of the party in a fair and equitable manner." This email was never answered. This can be a response by itself, "he said.
Mr Toibin also warned the party that in order to achieve a united Ireland "the party must be flexible, inclusive and inclusive".
Speaking to reporters at Leinster House, Tóibín said he would try to talk with the likes of Sinn Féin and Fianna Fáil and outside the parties who shared his views on the establishment of a new national group.
He said that people "are looking for an alternative vehicle, so that 34 percent of the population [who voted to keep the eighth amendment] have a voice ".
He said that this part of the electorate "is pushed to the margins".
He said he would see "if we can fold these people into a tight political organization that truly represents these views and we will work hard for these goals of a united Ireland and economic justice for people."
Any new party will not seek to reverse the outcome of the referendum but will seek to reinforce the laws on abortions currently undergoing by the Oireachtas, he added.
In a statement, Sinn Féin leader, Mary Lou McDonald, said that "all the elected representatives of Sinn Féin are bound by the ard fheis judgments.
"People voted to abolish the eighth amendment, and it is the responsibility of all the Sinn Féin TDs to put the people's vote into force and to represent Sinn Féin's policy, unfortunately, Peadar could not do that," he said.
Sinn Féin's deputy leader, Michelle O'Neill, said Mr Tóibín's resignation from the party was "unfortunate but not very surprising."
