Credit is due to the Guardian, who are the first of the mainstream press to make entirely clear that they sourced this story from blogs and include links to both The Daily and PoliticalHackUK.
They report that Short is working on a speech setting out her position in detail. The deadline for sitting MPs to inform the Party whether they intend to stand for reselection is the end of this week.
