I have been as critical as anyone of Gordon Brown's failure over the past 15 months to set out what 12 Labour MPs* writing in Progress magazine term "a convincing narrative." But as I have written in my Newcastle Journal column to be published tomorrow, the Prime Minister - and Harriet Harman - have had some good things to say this week about tackling inequality and social mobility, and the emergence of a "fairness agenda" over the past week offered some small hope that this long-awaited narrative had finally started to take shape.
So to my mind, Siobhain McDonagh's call for a leadership challenge to Mr Brown today is singularly ill-timed and presents a gift-horse to the Tories at the start of a critical conference season for Labour.
If the Prime Minister had hoped to mount an effective fightback over the next two weeks, based around some of the ideas he and his deputy have been airing this week, then Ms McDonagh's intervention this afternoon has probably killed it. Instead, the Labour conference in Manchester looks set to be dominated by yet more speculation about the leadership.
I hope she is bloody proud of herself.
* For the record: Janet Anderson, Karen Buck, Patricia Hewitt, George Howarth, Eric Joyce, Sally Keeble, Stephen Ladyman, Martin Linton, Shona McIsaac, Margaret Moran, Tom Levitt, and Paddy Tipping. I would say that only three of these (Anderson, Howarth and Joyce) are out-and-out Blairite loyalists, so speculation that they are part of a concerted Blairite plot is, in my view, probably misguided.
