An attempt to amend the constitution to allow same-sex marriage has been defeated in the Dáil by a vote of 36-10.
The amendment, to be voted on today, was supported by all parties, with Fine Gael, Labour, Sinn Féin, Labour-Sinn Féins and Independent TDs all voting in favour of the motion.
The motion was tabled by Fianna Fáil TD Niall Collins (Fianna Fail), with Sinn Fíin TD Michael McGrath (Social Democratic and Labour Party) also supporting the amendment.
In the Dail, TDs have a veto over amendments to the constitution, but this is limited to a simple majority.
The amendments were first proposed by former Deputy First Minister and TD David Stanton (Falkland Islands).
Mr Stanton said at the time that the amendment would allow the same-gender marriage issue to be addressed in the Constitution.
However, in a statement on Monday, Fine Gael said the amendment failed because the “diversity clause” was not included in the draft document.
The proposed amendment was defeated by a majority of 34 TDs.
