We have been here before. Under all governments, politicians tend to become dissatisfied with the processes of government. They are ready to assume that there is a solution: change the machinery. This is now back on the agenda. There are calls for turning No.10 into a Prime Minister’s department, for appointing outside experts as ministers without requiring them to be MPs or peers, for reducing the power of the Treasury and for shaking up the civil service as a whole, all in the interests of joined-up government. The underlying assumption is that if things are going wrong, the civil service is to blame. That is a fair summary of the views expressed by the Commission for Smart Government, in its new report.
