They play in the URC pro league with teams from Scotland, the four provinces in Ireland ( Ulster, Munster, Connacht and Leinster), Italy and South Africa.

England has its own league but every single team in it posted a significant financlal loss and rely solely on owners. A few have gone to the wall fairly recently including a fairly recent European Cup winner.,

France stands alone also.

I think the argument for reducing the regions again is to try not to dilute the Welsh talent pool even further and to keep as many welsh qualified players playing in Wales. England basically ban anyone from playing for England once they aren’t playing for a team in its donestic league.,
