The Taoiseach has told the Dáil that the Government supports the provisional application of CETA, a trade deal between Canada and the EU.
The Comprehensive Economic and Trade Agreement was expected to be signed tomorrow, but Belgium's federal government has so far failed to overcome a veto by the regional parliament in Wallonia.
Enda Kenny told the Dáil today the publication of the deal would be accompanied by a declaration that it would not affect public services, labour rights or environmental protection.
Fianna Fáil leader Micheál Martin called for a debate in the Dáil on CETA, telling members that the benefits of open, free trade for Ireland had not had been sufficiently viewed.
Sinn Féin leader Gerry Adams said his party had very real concerns about CETA, citing the rejection of the deal by Wallonia.
He said the deal was opposed by many NGOs, citizen groups and agricultural groups.
Mr Adams said the Government was ignoring the will of the Seanad, which recently passed a motion against the deal.
President of the European Council Donald Tusk, meanwhile, has said he remains hopeful that a planned EU-Canada summit to sign the deal will go ahead tomorrow, as Belgian politicians continue talks on the future of the pact.
Belgian leader Charles Michel hosted talks from early yesterday of regional authorities, including of Wallonia and Brussels, that have rejected an accord backed by all 27 other EU governments.
Without assent from its regions and linguistic communities, Belgium cannot sign the deal at the planned summit, which is to be attended by Canadian Prime Minister Justin Trudeau.
