TikTok has been confirmed as the inaugural title sponsor of the Women's Six Nations.

The social networking service will also be an official partner to the men's Guinness Six Nations and Autumn Nations Series from the 2022 season through to 2025.

TikTok says it amassed over five billion views for its rugby content on the platform, and plans to ramp up its focus on the Women's Six Nations content this spring.

"The significance of our partnership with TikTok cannot be understated," said the CEO of Six Nations Rugby Ben Morel.

"TikTok shares our ambitions for providing fans with the best possible experience and has the perfect platform for fans to access and engage with rugby throughout the year. Complementing this is the collective aim of giving the sport a global shop window to reach new and existing fans and put the likes of the Women's game in front of more people."

The Guinness Six Nations kicks off on 5 February, when Ireland host Wales in Dublin, Scotland welcome England to Murrayfield and France play Italy at Stade de France.

The TikTok Women's Six Nations starts on 26 March, following the conclusion of the men's championship. Ireland square up to the Welsh at the RDS in their opening clash.

Meanwhile, World Rugby has confirmed details of the qualification pathway for Rugby World Cup 2025 as the women's edition of the tournament expands to 16 teams.

Ireland failed in their campaign to qualify for the next year's World Cup in New Zealand, which includes 12 teams.

Under the new pathway, the RWC 2025 host nation will automatically qualify for the tournament with the four RWC 2021 semi-finals also securing direct qualification to the pinnacle event.

The 2025 host will be selected in May this year.

Should the host nation of RWC 2025 be a semi-finalist of RWC 2021 and win, only the remaining three teams will qualify for RWC 2025.

The next six teams will qualify via regional competitions by 2024, with winners in Asia, Africa, Europe, Oceania, South America and the newly established cross-regional competition, the Pacific Four Series, securing direct qualification.

Should the host nation of RWC 2025 win their respective regional competition, the next best placed team in that region will secure direct qualification.

The final opportunity to qualify for RWC 2025 will come via WXV, the new three tiered annual women’s 15s competition, with at least the top five ranked non-qualified teams at the end of WXV 2024 qualifying for the tournament.
