Babergh and Mid Suffolk District Councils Chief Executive Charlotte Adan is to leave the authorities in August.
Charlie, as she is better known, has been appointed as the new Chief Executive of The Royal Borough of Kingston upon Thames.
In a pioneering move, Ms Adan oversaw the integration of the award winning Smaller, Smarter, Swifter programme, which transformed the two councils’ workforces into one shared service.
The new structure created a more streamlined and flexible council that serves both sovereign authorities and their communities. In 2013, the two councils received an award from The MJ (Municipal Journal) recognising this work.
Cllr Derrick Haley, Leader of Mid Suffolk District Council said: “We will be sorry to see Charlie leave, but we are delighted that she has been appointed to such a prominent new role.
“Since her appointment as Joint Chief Executive for Mid Suffolk and Babergh five years ago, Charlie has been hugely successful in guiding the workforce of both councils through our ground-breaking integration and transformation process.
“Indeed, I have personally learned a lot through working closely with Charlie and am grateful that through all her efforts, she will leave behind a strong and dynamic organisation as her legacy, and her successor will be able to start from a solid foundation.”
Cllr Jennie Jenkins, Leader of Babergh District Council said: “It has been a privilege to work closely with Charlie over the last five years and there is no doubt that her hard work and determination has helped to put both Babergh and Mid Suffolk at the forefront of collaborative and transformational ways of working.
“By working constructively with all our partners and external stakeholders, Charlie has ensured everyone remains focused on delivering the very best outcomes for all our communities. We wish her every success in her new role.”
