In total, 8,194 members voted Yes to the deal, while 2,864 voted No.
Despite his opposition to the arrangement, Mr Ó Cuív signalled he would support Micheál Martin’s nomination for Taoiseach today and abide by the party whip. Fairer Future, the grassroots campaign group that organised against the deal, also stated its backing for Mr Martin but said the group’s work would continue.
Speaking after the result was announced, Mr Martin said he had spoken to Mr Ó Cuív. “I thanked them for their campaign and I thanked them for the very respectful democratic manner in which the campaign was conducted. Democracy in our party is alive and well,” he said.
He said the majority of the party were “very anxious we get on with the business of helping the country to get through this crisis”.
There was strong support for the deal in Mr Martin’s Cork South Central constituency, with 94pc of party members voting Yes.
There was also a high Yes vote (93pc) in Dublin constituencies including Dublin Fingal, where the party’s housing spokesperson Darragh O’Brien hopes to land a cabinet seat.
