Following Guido’s story yesterday about the Speaker’s spokesman abandoning her impartiality and attacking the Tories:

The spokesman needed a spokesman, and now she’s gone…

UPDATE: Here is the statement from the Commons:

“After a year in post Justine McGuinness has offered her resignation to the Speaker, which has been accepted. The Speaker thanks Ms McGuinness for her hard work and commitment over the last 12 months. She has contributed considerably to the running of the Speaker’s Office but now wishes to pursue other interests.”
