Was this Labour's Black Wednesday? Hardly. The Tories nightmare day in 1992 was horrendous because it affected every single voter - by hiking interest rates up to 15%. It destroyed the Tories' reputation for
competence in a stroke. The Clarke and Hewitt stories affect some people directly, but not everyone. And they erode Labour's image of competence, but they don't destroy it.
Nevertheless, this week's events do capture a mood - one of a government in a state of decay, no longer in control of events but buffeted by them. A resignation or reshuffle might dispel that mood for a while. But it won't go away - not until this government renews itself radically. And we all know what that will take.
