Not a revolution, but..
Well well. It only took until ten past one for the Blair issue to come up - raised by none other than Nick Brown - friend, ally but no relative of Gordon.
"We cannot drift on" he said (watch the interview here), before adding that the party had to listen to people and to avoid looking like an out of touch elite.
When asked whether Tony Blair could repair the problem he replied with a grimace - "he will have to try".
Not the start of a revolution, I grant you - but it was significant that someone who knows that his words are watched carefully spoke out so clearly and so early.
