I can't help feeling that the resignation of Environment Agency chairman Sir Philip Dilley was all a bit overdone. As chairman, he doesn't presumably actually involve himself in the day-to-day running of the place; that's the job of the chief executive. The chairman is supposed to set the strategic direction, which is not something you even really want to be thinking about in the middle of a major crisis. Frankly a beach in Barbados was probably the best place for him while there were major floods around.
Now you can certainly take potshots at Sir Philip for the general state of the Environment Agency, which appears to be both thoroughly incompetent and riddled with corruption, but he was at least an engineer by background. Take a look at who has stepped into his shoes, at least on a temporary basis: the green blob personified. Emma Howard Boyd appears to have made a career in "corporate social responsibility" and is a director of a green investment fund as well as having roles in any number of green NGOs.
It will be interesting to see if they keep her on.
