The question I want answered is:
Despite the huge controversy over cash for honours and the ensuing police investigation, you expect us to believe that none of the Labour party leadership asked those responsible for handling donations if there were any other arrangements in place which could be considered to breach the spirit of transparency underlying the legislation on public declaration of political donations even if they may have been considered to not breach the technical provisions?
If they asked, then it is inconceivable that nobody told them about donations that they clearly knew were questionable. If they knew about these donations, Peter Watt has set the precedent for what they need to do.
If they didn't ask, then they should resign for incompetence.
It seems that it was widespread knowledge throughout the Labour party that there was something questionable about these donations - Baroness Jay knew that a donation to Hilary Benn's deputy leadership campaign under the name Janet Kidd was from Abrahams and he refused it unless made by Abrahams directly. Mendelsohn, Brown's chief fundraiser knew at least a month ago (and given that Brown refused a donation to his leadership campaign from one of the front names for Abrahams there is at least a very strong suspicion he knew earlier - the explanation for turning down the donation, that the donor was not known to them, makes absolutely no sense as she would have been one of the biggest donors to the Labour party if the money she was giving had actually been hers.) but did not raise it with the police or the electoral commission and claims not to have mentioned it to Brown or anyone else within the party.
