This from Go-Ahead...
The Board of Go-Ahead Group plc (‘Go-Ahead’ or the ‘Company’) today announces that Keith Ludeman has decided to retire as Group Chief Executive of Go-Ahead after 15 years with the Company. He will retire on 4 July 2011 when he will be succeeded by David Brown.
As part of the orderly succession plan, David Brown, currently Managing Director, Surface Transport of Transport for London, will join the Company as Deputy Chief Executive on 1 April 2011 and will succeed Keith Ludeman when he retires.
So Tim O'Toole departed for First Group, then Ian Brown announces his retirement and now David Brown announces he is going to Go-Ahead.
Clearly retention of TfL Managing Directors is proving a challenge for Boris.
