No concerns on the hard border in NI then?
Turkeys voting for christmas comes to mind.
There won't a hard border between NI and Ireland. there really is no need as we have the Irish Sea between there and the rUk so the border / immigration / customs checks will be done at the ports and airports.
Can't see too many refugees transiting through cold and wet Ireland then risking a dip in the bloody freezing Irish Sea in a small boat to get to the rUK.
Now, if Scotland gets its Independence and the rUK is out of the EU and we are in, then feck me, that lovely outlet village in Gretna just off the A74/M74 will be repurposed in as quick as a flash of my arse in a kilt on a windy day to a customs and border checkpoint. Will be a right pain in the arse when I travel down south for work too (if they don't use enough KY on the customs search that is....)
