Sinn Féin Deputy Leader Mary Lou McDonald has said it would be unforgivable if other left-wing parties did not come together under the common Right2Change banner.
The party has signed up to the transfer plan drafted by the Right2Change campaign which will ask supporters to continue their vote preferences for other left-wing parties and independents - which could include People Before Profit, the Anti-Austerity Alliance and the Social Democrats.
Deputy McDonald today outlined the party's response to Right2Change, a broad coalition of trade unions, civil society organisations, progressive political parties and independents stemming from the Right2Water movement.
She confirmed Sinn Féin's support for the broad policy platform agreed by Right2Change.
Deputy McDonald said: "The Right2Water movement has evolved and grown from the initial sole concern around water charges to other issues.
"As a result of very long discussions and consultations, broad policy principles have been agreed which we in Sinn Féin are happy sign up to and to endorse.
"This policy provides a space for political parties and progressive independent candidates and a platform to fight the next election."
The Tánaiste has claimed political parties and independents planning to contest the next election under the Right2Change policy platform have fallen out before they even got to the church.
Joan Burton criticised the proposals of some of the parties involved before particularly significant in employers' PRSI.
She said: "In a situation where literally we are trying to get every single person back to work, I wonder to be honest about the wisdom of some of the proposals".
People Before Profit Leader Richard Boyd Barrett said the aligning of parties to the Right2Change group still had to be finalised.
Deputy Boyd Barrett said he expected this to happen in the next few days.
He said too that he is open to the principle to some type of voting pact between the parties involved.
The Right2Change policy platform is backed by six trade unions.
