Michelle McGlocklin, UK MD and chairman of the agency’s European tech practice, has left after more than 20 years with WS.
A spokeswoman for WS said that McGlocklin ‘decided the time is right to develop her career in new directions’.
McGlockin’s leaving follows the departure of head of digital UK Robert Anderson, who has joined Good Relations.
Well-placed sources suggested WS had initiated a pay freeze, although the agency declined to comment.
