Those questions will be answers about what is happening in the chaotic state of the Welsh domestic game.

The WRU is currently in the middle of cutting the number of Welsh professional teams from four to three by 2028.

The governing body has announced it will award licences to Cardiff and Dragons, pitting Ospreys and Scarlets against each other for the west Wales licence with a final decision expected by the summer of 2027.

New WRU chair Lyndon Faulkner came in and suggested he will look at everything, including keeping four professional sides, while he indicated he was a fan of an Anglo-Welsh tournament.

Now the WRU is trying to get a possible two sides into an Anglo-Welsh tournament, which was the number of professional teams the Union initially wanted to maintain when its reduction policy started.

The URC has been contacted by the BBC to see whether the WRU would face any legal action over lobbying to join another league, as it has committed to providing four sides to the current URC competition for another two years.

"There are some fundamental questions there," said Sweeney.

"We don't yet have a clear understanding of how they would legally exit the URC which they are a member of, so that has to be clarified in some detail.

"Going into cross-border competition has different ramifications and we have to be clear around the complexities."

When approached after Sweeney's comments, the WRU referred to a statement made last week: "Welsh men's professional teams compete in the URC and the WRU is committed to providing four teams to the URC until the end of the 2027-28 season.

"By the end of this season, the WRU will have determined the future operating model for the men's game in Wales.

"The WRU will continue to work with other shareholders in the URC on future Welsh representation in the competition.

"The WRU keeps under review the competition opportunities which may be available across the game and could be in the best interests of Welsh rugby.

"The idea of Anglo-Welsh competitions is something often debated by Welsh rugby fans.

"The WRU understands the appeal of the English top flight, which is why we are pitching for two of our women's teams, Brython Thunder and Gwalia Lightning, to be included in Premiership Women's Rugby."
