The  questionnaire can also be accessed from the RFU website homepage at www.rfu.com and Chief Executive Francis Baron said: "We have a number of concerns about the ELVs and the proposed process that is being followed regarding their introduction.

“As these Experimental Law Variations could potentially result in major changes to the Laws of the Game, the RFU believes it is important to consult those involved in the game at every level and give them an opportunity to express their views.

"In order to discover what participants in rugby union in England actually feel and to assist us in formulating the RFU’s response to the proposed changes, the Union has compiled an online questionnaire.

“I would urge everyone with an interest in the future of our game to go to www.rfusurvey.co.uk and spend ten minutes completing the questionnaire so we can paint as accurate a picture as possible of people's views in England when the matter comes up for debate at the IRB in May."
