A senior MP has accused the body running rugby in Wales of "bully boy tactics" after it announced its four regions would no longer be equally funded.
Welsh Rugby Union (WRU) bosses said they now intend to implement a new two-tier funding system.
Neath and Swansea East Labour MP Carolyn Harris said this was "totally unacceptable" and accused the WRU of failing to answer "fair questions" about the future of the clubs.
A spokesperson for the WRU said they "would welcome engagement with the local MPs and look forward to the discussion".
The governing body made the announcement amid reports it intends to cut a team from its professional tier, something it has neither confirmed nor denied, but said it would "welcome engagement" with MPs and looked forward to the discussion.
Wales has four professional regional rugby teams: Cardiff, Newport-based Dragons, the Ospreys in Swansea and the Scarlets in Llanelli.
WRU bosses intend to implement a new two-tier funding system after serving a two-year notice on the current agreement that underpins the professional game.
