Fianna Fail TDs have rejected an offer from Fine Gael to take part in a so-called 'partnership government'.
TDs from both parties met in Leinster House this lunchtime to discuss the plans - with Fine Gael accepting the plan laid out by Enda Kenny last night, but Fianna Fail TDs rejecting it.
One TD told Today FM that the offer was a kite being flown by Fine Gael, but that "this kite ain't going to fly".
The leaders of Fianna Fáil and Fine Gael have already met to exchange their responses.
In their second meeting Micheal Martin was also due to ask Enda Kenny to withdraw his apparent claim that a minority government 'would not work'.
But a spokesman for Enda Kenny said the Taoiseach had never made such a comment - and believes a minority government is not as stable, but is still an option "if necessary".
An overwhelming majority of Fianna Fáil TDs struck down the offer from Kenny, saying they were not prepared to coalesce with the party they campaigned against.
Similar opinions were expressed by many of the TDs elected - and the likes of Niall Collins and Willie O'Dea were simply not buying it:
However, on the way into the meeting, the likes of John McGuinness and Jackie Cahill were willing to consider it, particularly if there was a true 50-50 split in responsibility and positions:
Opinions on the Fine Gael side seem more straightforward, with TDs falling into line behind the offer made by Enda Kenny last night.
Today FM understands that everyone in the FG meeting who has so far spoken on the issue, has backed Kenny's offer.
The likes of Hildegarde Naughten and Marcella Corcoran-Kennedy were very much in favour of it ahead of the meeting:
One source told me that it would be 'irresponsible' of Fianna Fail to turn down the offer straight away, given how constructive Kenny had been with his approach last night.
But one minor complication is the fact that a so-called 'partnership' government - if it were truly a relationship of equals - would almost certainly include a rotating Taoiseach, where Fine Gael TDs would have to vote for Micheal Martin at some point in this Dail term.
Kate O'Connell was one TD who would find that a bitter pill to take:
