The newly-formed Celtic League has been branded a laughing stock by Llanelli chief executive Stuart Gallacher.
The 15-team competition - involving two Scottish districts, four Irish provinces and nine Welsh clubs - is due to start in August.
However, Gallacher is annoyed at the decision to increase the Welsh contingent from eight to nine clubs, a move which he says wrecks the business plans of hard-up clubs.
‘‘We have been let down by the Welsh Rugby Union,’’ he said.
‘‘We were told in the summer there would be eight Welsh clubs and this was confirmed recently.
‘‘Now we have had an about turn. It beggars belief.
‘‘We will be the only league in the professional game with an imbalance of numbers. It is an utter nonsense.
‘‘If this isn’t a reason for changing the structure of the Union, then God only knows what is. We are being governed by a body which is totally interested in the politics of the game and the sooner we get a management board to run the professional game the better.
‘‘The professional game in Wales isn’t about politics anymore. It may have been for the last 100 years but now it is a matter of running businesses to survive.’’
The league will operate in two pools, one of eight sides, the other of seven.
‘‘I am appalled about the way the game is being run in Wales by a general committee which is archaic and does not understand the professional game,’’ blasted Gallagher.
