McGrath, British-Irish has never been used. It's a new BBC coinage, and not a good one.

Ah, Snuffy, maybe that's the source - some army type who wandered into journalism and is bringing the ways of a different profession into the new one; not a good idea either!

No, Scots-Irish isn't used here, Poppa - though it's actually pretty accurate in a way, since the "planters" who were given the land stolen from the Irish in the 16th century and later were mostly Lowland Scots.
