The leaders of Fine Gael, Fianna Fail and the Greens are meeting in Government Buildings to sign off on a text to get a Programme for Government.
Negotiators from the three parties have been meeting over the last couple of weeks trying to reach agreement, and in the early hours of this morning agreed to a draft text.
However, there are a small number of issues still unresolved, and Leo Varadkar, Eamon Ryan and Micheál Martin are today attempting to address that and finalise a deal.
Once the leaders sign off on it, the deal will then need to be approved by the parliamentary parties - and Fianna Fáil and the Greens will then hold postal ballots of all their members.
It's expected that Leo Varadkar or Micheal Martin will become Taoiseach, before handing over to the other later in the Government's term.
However, it's not clear yet which of the two leaders would take the role first.
On his way into talks at Government Building today, the Fianna Fáil leader said he expected a deal will be signed tonight.
