The Fianna Fáil leader, Micheál Martin, is calling for the Taoiseach Enda Kenny to give a straight answer on when an election will take place.
Micheál Martin also says the Banking Inquiry must be allowed to finish its work and issue its report.
He was speaking as apparent tensions grow between Fine Gael and Labour over when the general election will be called.
If Mr Kenny decides to go to the country before the Banking Inquiry issues it's report, it will collapse.
Deputy Martin says the Taoiseach needs to give a straight answer.
He said: "I'm only asking for a straight answer. Of course they should be focussing on the job at hand, but they haven't been for the last while.
"But I think, in terms of if the Taoiseach comes in front of the Dáil and seeks an extension of time for the banking inquiry, then the very least he should do is be very honest with us and say 'yes it will report'.
"But the lack of straightness from him, it's very shifty kind of stuff, a nod-and-wink kind of approach inside in the chamber."
