Fianna Fail leader Mr Martin is set to be elected Prime Minister on Saturday, in a role he will rotate with incumbent Leo Varadkar of Fine Gael.
This will be part of a deal that will for the first time unite the two rival parties that have dominated politics in Ireland for over a century.
The move has come about after three quarters of Fianna Fail members backed a deal to restore a coalition Government in Ireland.
Fine Gael have also overwhelmingly endorsed the agreement.
Fianna Fail leader Micheal Martin said: “Democracy in our party is alive and well, and I’m delighted that the recommendation that I gave to the party membership, recommending this programme for government, has been so overwhelmingly endorsed by the party membership.
“I’m very grateful to the members for doing that and I think what it says to me is that the vast majority of the party are very anxious, and I’m sure those who voted against it are too, that we get on with the business of helping the country to get through this crisis.
“To engineer economic recovery in the aftermath of Covid-19, to deal with the ongoing health dimension and risks associated with Covid-19, but critically to get people back to work, to get the different sectors back to work, to create a better type of society, a greater quality of life for people.”
