England, Scotland, Ireland and Wales have gained control of their autumn fixtures as part of World Rugby's alterations to the women's global calendar.

The new WXV Global Series, which will replace the WXV competition, will run from 2026-2028 and feature the top 12 teams in the world.

Seeking to build on the success of the Women's Rugby World Cup in England, national federations and unions will be able to choose their own home and away games in September and October.

Alongside each of the home nations, Australia, Canada, France, Italy, Japan, New Zealand, South Africa and the United States qualify as the top 12 sides.

Those 12 nations are locked in to the WXV Global Series until the next Rugby World Cup in 2029.

Each side will receive the same amount of money from World Rugby to compete in the fixtures no matter how many Tests they choose to play.

Fixtures will be announced by each nation after the World Cup.

"This is really important in the context of [breakaway league] R360 and other competitions that are being discussed as we need to give the national federations, players and fans certainty," World Rugby chief executive Alan Gilpin said.

"This allows that certainty over a four-year cycle that allows the national federations and unions to go and have those conversations [on contracts] with the player groups. It is a really important milestone."

Teams ranked 13-18, who World Rugby describe as facing greater "financial challenges", will play their fixtures in a single destination in 2026 and 2028, funded by the global governing body.

Those teams are Brazil, Fiji, Hong Kong China, the Netherlands, Samoa and Spain.

This means WXV - a three-tier competition introduced in 2023 to supply more meaningful games before the World Cup - will no longer run.

BBC Sport understands the top 12 sides will play between 9-16 Tests in a calendar year, outside of World Cup years, with a maximum of six Tests.

The total of games will include fixtures played by home nations in 2027 when they also provide players for the first British and Irish Lions women's tour to New Zealand.

World Rugby says there will be over 100 games across the three-year Global Series competition and £9m will be invested, which is hoped will build on the World Cup in England that has seen record viewing figures and the final at Twickenham on 27 September sold out.

"The launch of the WXV Global Series marks another landmark moment for the women's game, following what will be an era-defining Women's Rugby World Cup in England," World Rugby chairman Brett Robinson added.

"It delivers on our commitment to raise standards, provide consistent and competitive fixtures, a clear international calendar that prioritises welfare, and create sustainable commercial outcomes for the women's game globally."
