Football League elections
At the end of the season, the bottom four of the Football League had to be re-elected to retain their place. Whilst in previous seasons the number of non-League applicants had been unlimited, this season saw the Football League Management Committee limit the number to two, with Wimbledon and Northern Premier League members Altrincham (who had finished tenth) entering the ballot. The top four in the vote would retain/win a place in the League.
With 27 votes, Wimbledon finished fourth in the election, earning a place in the League at the expense of Workington, who dropped into the Northern Premier League.
