Minister of State for European Affairs Lucinda Creighton has confirmed that the EU Fiscal Treaty Referendum is likely to take place in late May or early June.
The Cabinet are meeting this morning to finalise the date and an announcement is expected later.
Tánaiste Eamon Gilmore will announce the date of the referendum in a short speech to the Dáil, in the absence of Taoiseach Enda Kenny who is in China.
The treaty comes into force on January 1 next if 12 or more countries ratify it.
Minister Creighton said it is vital for Ireland's recovery that it is passed.
"I think the context of this referendum is extremely important," she said.
"Ireland has a good opportunity to send a strong message to investors, to potential partners - business people who want to do business in Ireland, not just from the EU but from around the world.
"I think that will be a very important consideration for Irish people and we all want to see the Irish economy recover."
