Ed Miliband says Labour needs to "face up to the scale of defeat" in the general election.
His brother David says: "we lost, and lost badly".
The clear implication is that Labour had no moral right in the eyes of the public to continue in power.
I think it is now incumbent on all those Labour-friendly commentators who were demanding a Lib-Lab coalition last week to either explain why the Miliband brothers are wrong, or to admit that they were advocating something that would have been inherently unstable and politically illegitimate. If we get silence we can presume the latter.
