Taoiseach Leo Varadkar has said he does not believe a no-deal Brexit is inevitable.
On a visit to Hillsborough Castle in Northern Ireland, Mr Varadkar reiterated the EU position that the Withdrawal Agreement was not open for renegotiation.
But the Irish premier insisted there was scope to offer clarifications on the deal and make changes to the Political Declaration on the future relationship.
"I don't accept it's unavoidable," he said of the prospects of a no-deal.
"There are many ways by which a no-deal can be avoided. Either by the ratification of the Withdrawal Agreement, a further extension or revocation of Article 50.
"So, there are a number of ways that a no-deal can be avoided on the 31st of October. I am certainly not fatalistic about that."
