Interim RFU chair Bill Beaumont, who, along with Sweeney, has been on a roadshow meeting club representatives, believes the chief executive’s critics “do not represent the wider views of our game”.
“A vote of no confidence risks sending the Union into paralysis and creating a costly leadership vacuum,” he added in an open letter urging clubs to vote for a review and against Sweeney’s removal.
The former England captain also reiterated that the board, with whom the chief executive’s fate ultimately rests, support Sweeney staying in his post.
“Any decision relating to the employment of the CEO is the responsibility of the RFU Board and the Board unanimously supports Bill Sweeney remaining as CEO,” he wrote.
“This support is based on his achievements to date, as well as his ability to deliver the RFU’s strategy while being highly motivated to respond and react to what we have heard from you, our members.”
