SIR DAVID Pepper, former Director of GCHQ, has joined Gloucestershire County Council as a non-executive director.
Sir David has agreed to work with the authority, to develop this new role, initially until next April.
Sir David will work with the council's officer management team to offer a fresh look at plans and performance.
Peter Bungard, Gloucestershire County Council's Chief Executive said: "We are already a top performing four star council.
"Our challenge now is to continue to improve with even more pressure on services and budgets.
"I am keen to look at better ways of doing our job.
"Sir David's experience of transforming GCHQ and his knowledge of Gloucestershire make him an ideal choice of non-executive director."
Sir David Pepper added: "I have lived in Gloucestershire for more than 35 years. It's a wonderful county and I want to see it prosper into the future.
"I am excited by this appointment and looking forward to working with Pete and his team.
"I hope I can use some of the lessons I learned at GCHQ to help them and the county deal with the challenges we face."
Sir David will be spending approximately two days per month with the county council.
Non-executive directors are standard practice in the private sector and increasingly common in other parts of the public sector such as health, but the appointment is thought to be a national first in local government.
