Hutchison will join MEC in October as one of five client service directors who between them oversee the agency's client relationships.
Steve Hatch, MEC UK’s managing director, said: "Paul has been in our sights for quite some time and we are delighted that he’s joining us. He has first-class senior client-handling experience, and also great strategic credentials too."
Hutchison joined Vizeum in 1991, leaving in 2005 to work at creative agency DLKW as planning director on its AA business.
He returned to Vizeum in 2006 as client director and, in 2007, was promoted to the media agency's management board, where he oversaw the HBOS, Heinz and John West accounts.
