Departing permanent secretary Chris Kelly joined the civil service from Trinity College, Cambridge and Manchester University. He spent 25 years at the Treasury, moving to the Department of Health in 1997, following a short period at the Department of Social Security.

Mr Kelly said last week: 'All organisations have to move on and adapt to changing needs if they are to successfully deliver services for the modern world. The organisational change is a natural development and it has my full support.'
