I think she was totally out of line with her comments about the Republic. She constantly goes on about how NI is part of the U.K. not Ireland and yet seems to want the south to play nice regarding Brexit and opportunities. The Irish Gov have denied talking down the NI economy in any way but in any case why would they not try to poach business?
Brexit will have serious impacts on the Irish economy through no fault of theirs and they need to try and gain some advantage out of it.
She can't have it it both ways. Saying the only hard border that exists is in the mind of the Irish gov is a ridiculous statement and an inflammatory one.
