David Moffett the Regional Rugby Wales (RRW) CEO has left his post with the former Scarlets CEO Stuart Gallacher taking his place.
Regional Rugby Wales was set up as a governing body to protect the interests of the four Welsh regions with regard to the WRU's activities but persistent issues with the WRU appear to have forced Moffet's hand. The pair blame the Welsh Rugby Union for what they say is a failure to reach a new WRU-regions participation deal.
"Welsh rugby still does not have the certainty of a solution it so desperately needs," said Moffett.
The statement read: "Gallacher... will take over the reins to continue the regions' negotiations with the WRU regarding a revised participation agreement that has so far failed to materialise."
Moffett was WRU boss before leaving that role to be succeeded by current chief Roger Lewis. There has been little progress on a new participation agreement for the regions with the WRU and the dispute has even gone to court.
"We're miles apart and that's the unfortunate thing," ex-Scarlets chief executive Gallacher told BBC Wales. "We are very concerned now. We had hoped that this would have been put to bed, certainly by the start of the Six Nations or indeed by the end.
"And here we are now going into June and still as far apart, probably, as we were three years ago. The stumbling blocks are player release, funding - all the conditions of the Rugby Charter that the WRU wants to put in we're totally against.
"We are independent businesses after all and the control that the WRU is seeking through the agreement is not acceptable to the four regions."
