Six rugby league teams from the NRL and English Super League will contest next year’s World Club series in England over three days in February.

Rugby league’s annual World Club Challenge will next year be expanded to include six teams from across the NRL and England’s Super League.

The premiers from each competition will be joined by two of their top-ranked rivals in the newly named World Cup Series, to be played in the UK from February 20-22 in 2015.

South Sydney and Brisbane have already confirmed their involvement, even if they don’t win this year’s NRL grand final.

Other NRL clubs have also expressed interest in joining the challenge.

The series will cap off a hectic pre-season for NRL sides, with the Nines tournament in Auckland, the All Stars fixture plus regular trial matches all scheduled in February.

NRL’s head of football, Todd Greenberg, said the expanded series would add even greater interest to the annual contest for the title of the best side in the world.

“Australian fans already love seeing the premiers go up against the best of Britain – but having three teams from each competition will really add to the excitement,” he said in a statement on Friday.

Super League general manager Blake Solly said he was delighted to host the series in England and expected “huge” crowds.

The schedule and ticketing details will be announced later this year.
