Almost 24 hours on, the British Prime Minister's Brexit speech was fresh in the mind of Sinn Féin's deputy leader during Leaders' Questions.
Mary Lou McDonald lashed out at what she described as "a wishlist" by Theresa May.
Ms McDonald said it was clear the speech was "bad news for Ireland".
She said it would bring an end to Britain's involvement in the European Courts of Justice, have a detrimental effect on the Good Friday Agreement and the economies North and South.
There was some advice for the Taoiseach from the Sinn Féin Deputy - to be assertive at the negotiating table with other member states.
Taoiseach Enda Kenny said the aim was to preserve the common travel area and ensure that there will be no return to a hard border.
He pointed out that Ireland would just be one of 27 countries negotiating.

Ms McDonald said giving a list of issues wasn't sufficient and accused the Taoiseach of sitting on his hands and chose to point out that the country goes beyond Dundalk, "into the exotic lands of Newry and as far as the Glens of Antrim". She called for a plan.
In response, Mr Kenny said the politics in Ms McDonald's commentary was "typical" of Sinn Fein, "without responsibility and blaming everyone else".
He said all the details aren't known because negotiations haven't started.
The Taoiseach said he was standing in the Dáil Chamber as a co-guarantor of the Good Friday Agreement and that he would work in the interests of all the people of Northern Ireland to defend that.
Other questions raised during today's Leaders' Questions included the report into Bus Éireann by Grant Thornton. An incredulous Robert Troy of Fianna Fáil questioned how it was possible that the Minister for Transport had not read the report.
He noted that he left a copy in the minister's pigeon hole last night. The Taoiseach said Mr Troy was being "very hard" on Mr Ross at the start of the Dáil term, which led to some laughter.
Independents4Change TD Catherine Connolly highlighted the fact that Galway University Hospital, which services one million people, - is at "crisis point" and operating in a "code black alert".
Ms Connolly said people are falling ill and dying and due to a lack of investment.
The Taoiseach confirmed to the Dáil that the Minister for Health Simon Harris wants to visit the hospital in the coming weeks to look at possibilities for development of facilities such as Merlin Park Hospital.
Galway was also the focus of the Independent TD Noel Grealish - he raised the increasing problem of traffic in the city.
Mr Grealish pointed out that the Galway city by-pass will open until 2026 and questioned if the city would be expected to come to a standstill in the meantime.
The Taoiseach said there was no single panacea for Galway and the priority was to implement the transport strategy.
