Jim,
"Republic would benefit."
Since when has it vbeen the job tof a Little Brit to decide what i best for Ireland

I meant the UK would be losing revenue but the Republic would make out of it.

DMcG,
Things are only 'help' if both sides agree they are helpful

One side does not want to be helped.
They want to use the threat of a hard border as a negotiating tool, even though it would hurt their side too.
