Only one club will be relegated from the National North League at the end of this season.
The same will apply to the National South League.
The reason is that the FA wish to balance various leagues after the problems at Bury and Macclesfield.
Three teams will be relegated from the National League this season and four teams promoted into it, two from the North and two from the South to bring it back up to 24 teams.
From the 2022-23 season, both of those divisions will increase to 24 rather than 22 teams.
