The Taoiseach has set Ireland on a collision course with other EU countries - saying they must all have a say in Britain's exit talks.
Enda Kenny was speaking ahead of a mini-summit between the leaders of France, Germany and Italy to discuss the Brexit process.
The Dail has been recalled this lunchtime to discuss the Brexit vote and its consequences for Ireland.
The Taoiseach said he wants a common agreed response across the political parties in Ireland - but warned it's not possible to fully implement contingency plans, as Britain's proposed arrangements remain unknown.
The Taoiseach took a swipe at a meeting of the founding members of he EEC over the weekend where they pushed for a speedy exit by the UK.
Fianna Fail's Micheal Martin said everyone in Ireland needed to be on the same team, though Sinn Fein's Gerry Adams said the first response of Ireland should be to acknowledge the outcome of the vote in Northern Ireland, where a majority opted to Remain.
Meanwhile the aftermath of Brexit continues to cast a shadow over financial markets - with the ISEQ index of Irish shares down by over 7 per cent this lunchtime.
In advance of that fall, however, Michael Noonan said the reaction of the financial markets was to be expected and that there was no evidence of any "panic" over the fallout.
