General election
Harold Rushworth was originally declared the winner of the general election.Cause of by-election
Supporters of Allen Bell filed a petition to the electoral court complaining of voting irregularities. Bell, however, claimed that he would take no part in any attempts to upset the election, leaving it up to his supporters. This petition was ultimately successful and it was announced by the court that a by-election should take place for the seat.Selection process
Both Rushworth and Bell decided to run again for the seat. The Labour Party refused to put up a candidate, believing that the two candidates who had tied with each other should compete in the by-election.Result
Rushworth won the by-election. This by-election clearly created much interest as the turnout was higher here than it was at the general election. Rushworth's improved showing can be put down to the fact that he got most of the votes that were previously cast for Hornblow.References
