The WRU and the RFU are in talks to form at least one new competition that would involve clubs from both nations.
The EDF Energy Cup is likely to make way for the new format and the change could happen as early as next season, according to sources.
Roger Johnson from the WRU commented, “There is a shared desire among the RFU and WRU to preserve Anglo-Welsh encounters to enhance existing competitions. But Anglo-Welsh matches must complement Celtic rugby and we are also determined to develop the Magners League.”
