Regional Rugby Wales boss Stuart Gallacher has resigned from the boards of the Pro12 and ERC as Welsh rugby's crisis continues.
Gallacher previously represented the four Welsh regions - the Blues, Dragons, Ospreys and Scarlets - on the boards of the Celtic League and European Rugby Cup.
With the future of the regions uncertain given speculation linking them with a move to join an Anglo-Welsh league, Gallacher's resignation will further the belief that the regions plan to join the English league and the new European competition proposed by Premiership Rugby.
Earlier this week the regions called for an independent enquiry regarding the distribution of commercial revenues between the unions and regions.
The news is just the latest chapter in the ongoing saga to decide the future of Welsh rugby, with leading stars including Sam Warburton, Leigh Halfpenny and Alun Wyn Jones all out of contract at the end of the season.
