Personnel or policies?
By no means everyone in the Labour Party believes that the party's problems will be solved by changing leaders or setting out a timetable. Some believe that the problems are more a matter of policies than personnel.
Foremost amongst those is Charles Clarke, who gave an interesting lecture this morning expressing scepticism about the need to renew Trident or build nuclear power stations; backed green taxes and the completion of House of Lords reform and much more besides. You can read his speech here (word document) or watch my interview with him here.
PS: Now another letter's being planned. This one says that MPs back David Miliband's prediction that the PM will be gone by this time next year. More on this later.
