A leading editor has claimed the Irish government has "real fear" Britain is not prepared to delve into the details of Brexit.
This follows reports that the Irish Taoiseach wants immigration checks to be performed at Irish harbours and airports, to effectively create a border on the Irish Sea rather than between the two countries on the mainland.
Leo Varadkar is supposedly unconvinced by Theresa May's plans to implement a hi-tech border between the Republic of Ireland and Northern Ireland, as he's said to believe this could endanger the ongoing peace process.
Bernard Purcell, the editor of Irish World, said Irish officials remain afraid the UK is not adequately prepared for the EU withdrawal.
He told Julia Hartley-Brewer there is a solution to the border issue, but it requires serious, long-term planning.
"The big fear at the moment," he added, "is that this is just been pie-in-the-sky wishful thinking on this part of the Irish Sea [in Britain], that there has been no serious prep work done.
"Ireland started its own contingency plans, even though it preferred not to see Brexit, a year before the referendum. A year ago, after the referendum, there was some dismay that very little, if any, work had been done in Whitehall to prepare for the consequences.
"There is big fear among Irish officials Britain is not prepared for the sheer, vast amount of grinding detail needed in the preparations for Brexit.
"It’s [Irish government] not going to settle for that, it needs a clearly defined position and the blessing and benediction of the rest of the European Union.
