The Fine Gael leader Leo Varadkar has said policy discussions with the Green Party have started well.
The two parties are meeting today and tomorrow to discuss the common ground they might have with regards to government formation.
The Taoiseach has said so far initial talks with the Greens are going well.
He said: "I don't want to talk too much about it in the media but certainly it started well.
"The approach that both parties took to it was that it would be an open policy exchange where we would talk about our policy similarities, our common objectives and also our differences and tease them through.
"I think the atmosphere is very good, actually, and it was very different to the Dáil which is so confrontational.
Fine Gael will also meet with Fianna Fáil later in the week.
The Greens, meanwhile, have been holding talks with a number of parties - including over seven hours of policy discussions with Sinn Féin last week.
Party leader Eamon Ryan has said there is a "willingness amongst the other leaders to engage with the Green Party and the increased mandate of the party".
