HOPE not hate publicly described itself as supporter-funded and registered with the Electoral Commission as a third-party campaigner, and it also said its Makerfield campaigning was carefully tracked to stay within the relevant spending limits. Electoral Commission guidance says spending only counts as being made "on behalf of" a candidate if the candidate or agent directed, authorised, or encouraged it; the public sources I found do not show Andy Burnham or his campaign authorising HOPE not hate’s spending. So the claim that this spending represented spend accrued on behalf of the Burnham campaign is not supported.
