The future of the Lions has been declared safe by chief executive John Feehan following last Saturday's triumph over the All Blacks.
Time constraints and demands for more money from clubs have threatened the Lions concept, but Feehan yesterday insisted that tours are only going to get "bigger and better".
South Africa will host the Lions in 2021 and, while there is pressure to reduce the itinerary to five weeks, the powerbrokers are confident of negotiating a deal with their stakeholders.
"Every business has risks, threats and opportunities and the Lions are no different," Feehan said. "More people support the Lions than at any other point in history and I see a vibrant future as there are few things that compare to them."
Feehan said there were no plans to move away from the traditional four-year touring cycle of South Africa, Australia and New Zealand.
