Hugh Milward will leave his UK head of public affairs post next month to become deputy MD at Malcolm Gooderham's expanding agency.
Milward moved to the fast food giant's UK headquarters in 2006, having previously held senior posts at Weber Shandwick and the Learning & Skills Council. He also worked on Ken Clarke's Conservative Party leadership bid back in 1997.
Milward takes the title deputy MD, corporate, at TLG. His move comes as the agency creates new capacity in Scotland and Brussels, with the hire of former Downing Street director of political operations John McTernan and former Asda PR chief John Longworth.
Both McTernan and Longworth have been drafted in on a part-time basis to help get the new offerings off the ground.
McDonald's retains Portland for external public affairs help in the UK. The company's VP of communications Nick Hindle is leading a search for Milward's successor.
