The Welsh Rugby Union and the four regions have established a new body to strengthen the professional game in the country.
In a move to confront the major issues facing the sport in Wales, a High Court judge - Justice Wyn Lewis Williams - will chair the new Professional Regional Game Board (PRGB), which will include representatives of the WRU, Newport Gwent Dragons, Cardiff Blues, Scarlets and Ospreys.
The board has been established in the wake of a critical report into the way professional rugby is run in Wales and it is hoped the new organisation can work to improve the situation at the elite level both on and off the field and address various issues including the continued exodus of top-level players.
A report by PricewaterhouseCoopers painted a dark picture, with the current system of four regional teams deemed "financially unsustainable".
"The formation of the new Professional Regional Game Board is a landmark moment in the history of Welsh rugby," WRU chief executive Roger Lewis said in a statement.
"By working together, we will create a unity of purpose for Welsh professional rugby which will be underpinned by collective management, enhanced with greater central resources and structured to ensure effective decision-making."
61-year-old Williams played for Tylorstown RFC and joined the International Rugby Board's disciplinary panel in 2012. He plans to undertake his new unpaid role on the PRGB alongside his legal career.
"His status as a High Court judge ensures he takes on this post with a formidable reputation for objectivity, fairness and an undoubted ability to find intelligent solutions to complex problems," added Lewis.
"His interest in rugby and true understanding of the game at all levels means he brings to the role a real knowledge of the issues which the PRGB will prioritise."
The PRGB is expected to hold its first meeting later this month.
