The WRU letter also said financial and commercial stability as well as governance integrity would also be in jeopardy, which it claimed would “drag Welsh rugby back to outdated structures and a return to debilitation factional internal politics”.
A previous EGM was held in 2023 where the clubs backed proposals to modernise the board with more independent selected members rather than elected candidates.
Central Glamorgan has responded by accusing the WRU of scaremongering.
“The call for an EGM does not undermine any governance stability, we are not asking for any governance changes that were implemented in 2023,” it said.
“This WRU statement is just another scaremongering tactic for clubs not to support an EGM.
“People in power can use scaremongering as a tactical tool to gain support and control the agenda. Fear is a powerful emotion that can bypass logical reasoning making people more susceptible to manipulation.
“We live in a society where we have a democratic right to call an EGM and should fear no reprisals or repercussions from doing so.”
The WRU stated it had “turned a financial and governance corner in the past two years and independent experts have confirmed our significant progress”.
Central Glamorgan said ‘while finances have increased, investment into the game has not improved greatly’.
“All we are seeing is an increase in the organisational structure, overinflated salaries, the use of consultants and no progress at all,” it said.
“Money is not being invested properly into the core product which is rugby.”
