The news that Steve Hilton is taking a leave of absence of at least 12 months from No.10 will obviously mean changes of policy, of emphasis and of tactics in Downing Street Operations. The Telegraph has a good review of many of the themes that Hilton championed, few of which will be missed by the Lib Dems.
Two appear to have been missed.
Firstly, Hilton was the great champion of Behavioural Economics in Downing Street, as exemplified in the book and later the blog 'Nudge' (which is very much worth a visit from time to time). Here's a report from the Cabinet Office on how the government is using Behavioural Economics to reduce fraud. Will anyone still pursue this going forward?
And secondly, of course, Hilton was the father and champion for 'The Big Society'. Cameron is, by all accounts, still a huge fan of the idea, but it has never been properly explained nor defined. And with Hilton gone - that may well be the last we hear of it.
