Writing today for CSW in our annual permanent secretaries' round-up, Kerslake says: "In terms of our own reform agenda, we need to identify and agree with ministers the priorities for change and then organise their delivery.
"The civil service has immense strengths but also needs to adapt to a new world with new expectations. This will require strong corporate leadership towards a shared endeavour."
Meanwhile, new cabinet secretary Jeremy Heywood urges civil servants to "embrace techniques such as 'nudge', transparency and innovative funding models."
