The most revealing comment Baume makes, though, is about public sector pay:
"There is often no rhyme or reason for a salary level being offered. There really is no logic to why a Permanent Secretary might be paid a £180,000, a local authority chief executive £250,000 and a university vice chancellor £350,000.
People in this country have a strong sense of fairness. I don't believe they begrudge many senior salaries. They understand that hospital chief executives or permanent secretaries are running large complex organisations.
I hope we will see even fewer of those of the eye-watering salaries - and off-the-books contracts - that have been offered in recent years to some appointments to the civil service, sometimes twice the salary of the Permanent Secretaries themselves."
