While the new tournament has been confirmed, there is no indication as to how many tests it will add to each nation’s respective schedules.
A second-tier competition will also be run, with promotion-relegation matches being explored - at this stage, these matches aren’t expected to feature until 2030 - to give the emerging nations an opportunity to earn their way into regular test rugby against the world’s best.
The second-tier competition will feature teams from Europe and the rest of the world, with Sanzaar and the Six Nations actively involved in cementing the link between the two divisions.
“Establishing the two competitions will pave the way for promotion and relegation matches, contributing towards a valuable pathway for teams, and will support ambitions to sustain and grow the global game,” a joint statement released by the Six Nations and Sanzaar said.
Confirmation of the new venture comes after long-standing reports the two parties had been working on establishing a World Nations Championship. The Telegraph reported in March that the blueprint for the tournament had been agreed, and since then players, leagues and major stakeholders had been consulted about the endeavour.
“The introduction of the new elite international competition is testament to the strong ambition across all parties, motivated by delivering context and a stronger narrative around the July and November windows, that can excite players and bring new fans to the game,” the statement said
“The impact this will have on the game will be to drive its growth and long-term sustainability. This runs alongside the work being done to add greater clarity and balance to the club and international calendar; a process Sanzaar and Six Nations Rugby remain committed to help deliver.”
