George Culmer, director and chief financial officer of insurance firm RSA has announced plans to leave the company to become group finance director of Lloyds Banking Group. A final date for the transition has not been set. The news came amid a flurry of personnel moves at Lloyds, including the designation of an interim chief executive in the event that António Horta-Osório, who is currently on medical leave, does not return by the end of December.
