The agreement will result in the 2018 Championship being named as the NatWest 6 Nations, which will open with Wales hosting Scotland at Principality Stadium on 3rd February.
As one of the family of brands owned by RBS, this agreement will extend Six Nations Rugby’s partnership with the business.
Welcoming the partnership, Six Nations Rugby CEO John Feehan said: “We are delighted to be announcing NatWest as Title Sponsor of the NatWest 6 Nations and the extension of our relationship with RBS,” he said. “They have been excellent partners over the past 15 years and we know what an outstanding role they have played and will continue to play in the success of our Championship.
“I am sure it will be a wonderful event in 2018 with NatWest on board. They know how this great Championship works and there is no doubt that it is a very positive development for both us and for NatWest ahead of next season. We greatly look forward to it.”
Commenting on the sponsorship, David Wheldon, Chief Marketing Officer at NatWest said: “We have been title sponsors of the Six Nations for the last 15 years and are delighted to be renewing our sponsorship for a further year under our customer facing NatWest brand.
“The 2018 NatWest 6 Nations will provide us with a platform to engage and build affinity with our customers and to offer our continued support to a sport with which we have had a long running and mutually beneficial relationship. The Six Nations also has a strong European reach where we also serve our customers through our NatWest brand.”
