The Union said it would consult on a reduction to three or two regions to ensure Wales has “teams that can compete” at the top of the professional game.

The shake-up also comes after the men’s side suffered its worst season with nine defeats in 10 games that drew a total losing sequence of 18 matches, a run that only ended last weekend with a 31-22 victory in the second Test against Japan.

“The current rugby system in Wales, which includes national teams, professional clubs, community clubs, academies, universities and schools isn’t delivering consistent success on the field and isn’t currently financially sustainable given the likely investment required, even with the recent actions taken to increase financial resources,” the WRU said.

“The WRU is therefore considering a more radical strategy focused on maximising investment and reforming the whole structure of professional rugby in Wales, amongst other options.”
