The top-level league is the 12-team Super League, which was reduced from 14 teams due to a major reorganisation of the professional leagues in 2015. Ten teams are based in the heartlands, with the other teams in France and Canada. Below Super League is the Championship, with 14 teams, and League 1, with 11 teams. As of the next season in 2020, the Championship has twelve teams from the heartlands and one each from London and France; League 1 has six heartland teams, three teams from Newcastle, Coventry and London, and two from Wales – one in the North and one in the South West.
