Former taoiseach John Bruton has challenged the Democratic Unionist Party and the UK government to spell out exactly the sort of Brexit they want.
Mr Bruton said that neither had “come forward with their own ideas” on issues such as the Irish border or remaining in the customs union after the UK leaves the European Union.
He added that the English overruled the wishes of Northern Ireland and Scotland and they now need to “change their opinion”.
Last week, Taoiseach Leo Varadkar said Ireland would not help Britain design an economic border for Brexiteers, comments which DUP leader Arlene Foster yesterday described as “not helpful”.
He said Brexiteers were the ones who wanted a border, so it is up to them to design one.
Speaking on RTÉ’s Morning Ireland, Mr Bruton said while it looked likely that Brexit would now happen, “we have to do everything we can to stop it happening, if we can”.
“Really, it is the English. They have to change their opinion. They have initiated Brexit. The opinion in Northern Ireland was against Brexit, and the opinion in Scotland was against Brexit. That has been overruled,” he said.
Mr Bruton added that the DUP should be more up-front with its own Brexit ideas.
“Some hard questions have to be asked. What sort of Brexit do they want? Do they want the UK in the customs union? What sort of agricultural policy do they want, because that will be very important at the border,” he said.
Mr Varadkar is due to meet Stormont’s political parties tomorrow on his first visit to Northern Ireland since becoming Taoiseach.
