Well firstly, this has to be one of the most poorly executed coups of all time, it does not have a figurehead and some of its potential supporters have not even been contacted. What exactly is the plan here, ask people to send a response whilst not putting up an alternative? All the while, Brown and his henchmen have been able to cajole senior figures into backing him publicly.
Secondly, we have all seen the letter, I published it here, so if you are a Labour MP, who wants to sign it, just print a copy on your letterhead, sign it, scan it and email it. Simple. I am not sure what the benefit is of being interviewed on TV news and supporting the need for a change of leader, and then not sending an email will achieve? The whole world knows the email address. Or is there some kind of etticate and engraved stationery required with leadership challenges?
With Alan Johnson becoming Home Secretary, and David Miliband keeping his job in the Foreign Office have the email plotters lost their chief candidates to replace Gordon Brown? And if not, who is there left who is both credible and willing?
