It is a good move but, in line with my previous contribution, the obvious problem of Brexit immediately presents itself, specifically whether the UK will be compliant within this landmass, for example, people running with their children from Lifford to Strabane. I am not trying to be facetious, but what overt and immediate problems can the Tánaiste foresee as a result of Brexit, in particular for families living along the Border corridor?
