Sinn Féin leader Gerry Adams has welcomed the fact that the Taoiseach expressed impatience with the British government.
Enda Kenny appeared to display irritation that London was still vague about what exactly its relationship will be with the EU, in particular its attitude to membership or otherwise of the EU customs union.
Speaking ahead of a Sinn Féin Ard Chomhairle meeting in Dublin this morning, Mr Adams welcome the development but also accused Mr Kenny of being too slow and of waiting to see what the British do.
He added that it should be about what the Irish Government does.
Mr Adams also said phrases like 'a seamless border' or 'friction-free border' are absolutely meaningless.
He said if the British have their way we are going to have a hard economic border on this island, which will devastate agriculture, commerce and jobs.
Meanwhile, the Sinn Féin leader in Northern Ireland has said they have had a week of critical discussion and ongoing negotiations on restoring power-sharing at Stormont.
Michelle O'Neill said her party is coming at talks with the right attitude and they want others to do so also.
She said they will work with DUP leader Arlene Foster during the negotiation process, but said the former first minister cannot put herself forward to resume that position or become deputy first minister while there is a cloud hanging over her.
She said they need the inquiry on the Renewal Heat Incentive scheme to report and that position is clear.
The RHI scheme led to the collapse of the Stormont Assembly and last week's election.
