The Government is opposing a bill calling for neutrality to be enshrined in the constitution.
Solidarity - People Before Profit want to force any future Government to have to hold a referendum to end Ireland's long-standing policy of neutrality.
Currently Ireland is militarily neutral, however it is not covered in the constitution.
In light of the war in Ukraine, Ireland contributed to an EU fund for non-lethal assistance, which includes ready-meals and armour but did not fund weapons because of this military neutrality.
It comes as senior coalition members have been questioning the future of that policy in light of war in Ukraine.
Foreign Affairs Minister Simon Coveney believes putting neutrality in the constitution would mean ending many of the things Ireland currently does, like providing money to other countries involved in war:
"It could prevent a current or future Irish Government from using the instruments and tools at our disposal - either bilaterally or through the EU to give practical expression to our foreign policy.
"To be blunt - it would stop us putting our money where out mouth is."
