Huddersfield Giants and Warrington Wolves have been elected to the Women’s Super League for two years from 2020.
Both sides contested the recent Championship Grand Final at the Manchester Regional Arena in October, which Warrington won.
No sides will be leaving the competition, meaning it is another season of expansion for the top women’s competition, as ten teams will compete in 2020.
Thomas Brindle, the RFL’s head of growth, said: “This is another positive step in the Betfred Women’s Super League success story.
“The expansion to seven clubs in 2018 and eight in 2019 has undoubtedly enhanced the stature of the competition and of women’s rugby league.
“We have a significant goal of increasing the number of women and girls playing rugby league to 21,000 by 2021 — when England will host the Women’s World Cup alongside Men’s and Wheelchair competitions.
“The England team are currently in Papua New Guinea on a ground-breaking tour, which is an important part of their World Cup preparations following their appearance in the World Cup Nines in Sydney last month.”
