Few politicians have put as much thought in to the team around them as George Osborne. He is a collector of talented people. Unlike most Tories, he has gone outside of CCHQ and parliament for nearly every senior appointment he’s made. But I understand that after Christmas he’ll be losing one of the most important members of his operation, Poppy Mitchell-Rose.

Mitchell-Rose has acted as Osborne’s fixer and gatekeeper since he first became shadow Chancellor. On the long—and sometimes bumpy—road from opposition to government, she has been a calm sherpa who has dealt with a host of problems before they have even arisen. But she is now moving to Washington, DC, before starting a career in the private sector. I suspect that she’ll not be short of job offers.

Mitchell-Rose’s Special Adviser position will be taken by Thea Rogers, who is currently the BBC’s lead political producer. She’ll have a particular emphasis on the broadcast presentation of Osborne’s economic and political strategy. She’ll fit in alongside Ramesh Chhabra, Osborne’s political spokesman who is in charge of daily news management for the Chancellor.
