Nick Robinson has just reported on the Today Programme that Jon Mendelsohn had been told by Peter Watt, the Labour Secretary General who has already resigned over this scandal, how David Abrahams was making these donations to the Labour party. Mendelsohn was unhappy with the arrangement but reportedly did not inform the relevant people at the electoral commission of it but instead sought to resolve it himself which is apparently why Abrahams received a handwritten letter from him on Monday. Now, Mendelsohn has not yet confirmed this or spoken to Robinson but if true it transforms the story. George Osborne has already demanded Mendelsohn’s resignation. Realistically a decision has to be made on this before Prime Minister’s Questions at noon.
