[6] Labour's decision to call for a by-election before Dobbin's funeral was criticised by Paul Nuttall and Steven Woolfe, UKIP MEPs for North West England, with the former describing it as "shoddy politics".

Labour MP for Chesterfield Toby Perkins defended the timing, saying "With the agreement of Jim's family, we have moved the writ today as it is vital that the people of Heywood & Middleton constituency are not left without representation for an extended period".

[7] UKIP candidate John Bickley distributed a leaflet in which he said "Labour's betrayal is no more apparent than with the young white working-class girls of Rotherham and Rochdale where rather than upset immigrant communities, years of abuse were ignored and complaints swept under the carpet".

[13] The UK Independence Party announced on 11 September that their candidate would be John Bickley, a software businessman who had stood in the Wythenshawe and Sale East by-election in February, in which he had come second.

[14] The Green Party announced their candidate on 14 September as Middleton resident Abi Jackson, a recent graduate of the University of Huddersfield with a master's degree in psychology.
