Mr Varadkar announced his resignation in February but has remained as an interim leader until a new government is formed.
Ireland’s hung parliament entered deadlock over the choice of a new premier following a tight election.
Fianna Fail leader Martin is set to take over from Mr Varadkar before handing over to Fine Gael’s leader, the party’s finance spokesman Michael McGrath said.
Statements from Fianna Fail, Fine Gael and the Green Party said: “The leaders have signed off on the draft Programme for Government and it will issue later this afternoon.
“The respective parliamentary parties will be briefed on the programme this evening.”
The Programme for Government states: “This is a defining moment for our country.
“We face urgent challenges which touch every community. In the space of a few short months our world has turned upside down.
“Lives have been lost and hearts broken, and our lives and livelihoods have been changed utterly. In striving together against something which threatens us all, we have shown we can surprise ourselves – adapting quickly, building new alliances and collaborating in ways we never expected.
“All to realise a common purpose: our common future.
“COVID-19 has presented the global community with a terrible set of challenges to add to the ongoing climate and biodiversity emergency.
“In this Programme for Government we are asserting our ambition to meet these challenges, repair the damage that has been inflicted by the pandemic, and take the renewed spirit arising from these challenging times and translate it into action.”
