A new report from the Institute for Government on policy churn – the perennial question of why government policy seems to be replaced and reinvented with what is sometimes extraordinary rapidity. There are some sensible ideas on how to do this better, though the idea that strengthening the centre will slow down the churn, rather than accelerate it, might be seen as rather optimistic by some. But it’s essentially looking at the symptoms rather than offering ways of addressing the underlying causes, with little obvious reason to expect much to change.
