Much comment in the MSM and blogosphere alike today over the leadership chances of Harriet Harman as she stood in for Gordo at PMQS. The Sun reckons she's already plotting to take over, as does Andrew Rawnsley. Mike Smithson on Political Betting rates her chances, but Ben Brogan thinks she's already blown it. Iain Dale suggests Jack Straw could be in on the plot, while a thoughtful Tory perspective comes from new-kid-on-the-blog Alan Collins.
So what do I make of it? Well, if Harriet Harman is seriously being talked about as the answer to Labour's problems, it merely demonstrates the depth of the crisis the party is in.
Harman is political Marmite - she has her very strong admirers among a certain stratum of politically-correct London society - but she is not, and never has been, generally liked by the broader mass of the British public.
This did not really matter when Labour was choosing a deputy leader. The job of deputy is more about reassuring the faithful than reaching out to the uncommitted. But it will matter if and when the party comes to choose a new leader - particularly after their experience with Mr Brown.
I suspect that Harman knows this, and that her comment at PMQs about there not being enough airports for the men who would leave the country if she became PM displayed a certain degree of self-awareness.
Her primary objective in any leadership battle will be, firstly, to hold onto the deputy leadership - a generational shift in the leadership, for instance to David Miliband, could make her a casualty along with Gordon - and to secure the sort of senior role in the next Cabinet that Gordon has denied her.
I suspect her real aim is to be Justice Secretary rather than PM, but letting the speculation ride for a bit will do her no harm in this context, as it underlines her claims to be seen as a "key player" and strengthens her position for the inevitable job bargaining that will accompany a leadership change.
My guess is that she will eventually throw her weight behind the "Anyone but Miliband" bandwagon that appears to be growing and back the candidate most likely to give the Foreign Secretary a run for his money. As things currently stand, that surely means either Straw, or Alan Johnson.
