Damian Hopley has warned rugby chiefs they could face another backlash if they ignore the views of the world's leading players in any plans to expand the Six Nations by including South Africa.
Hopley, chief executive of the Rugby Players Association which looks after England's leading players, believes the failure of World Rugby's plan for a Nations Championship which was due to start in 2022 should act as warning to those bidding to create a new-look championship in Europe.
Ireland captain Jonny Sexton, in his role as president of the International Rugby Players' Council, last year led the chorus of disapproval from the sport's leading players for the Nations Championship and Hopley is confident the united front delivered in the face of that threat to player welfare would be triggered by any change to the Six Nations that increases the demands on those taking part.
A Seven Nations, shoe horned into an already packed Northern Hemisphere schedule, would put extreme pressure on players with an expanded championship giving the competing teams just one week off.
