PRWeek broke the news of Fox standing down from the chief executive position ahead of the move in December.
He had been in the role since July 2009, having been hired as director of policy and comms the previous year, during which time he helped oversee the party’s move into coalition government.
In an internal email to Liberal Democrat colleagues, Fox said there had ‘been few dull moments’ during his three-year spell with the party, adding: ‘I am looking forward to getting back into engineering and working for one of the great businesses based in the UK.’
Fox told PRWeek that the creation of the post would help to spread the group’s message.
He said: ‘I have had a long career in engineering and manufacturing business and GKN is up there with the best – it’s got a fantastic history and great future.’
Fox had previously been director of corporate relations for Tate & Lyle and director of group comms at technology firm Smiths Group.
GKN, which primarily operates in the automotive and aerospace industries, hired Michael Turner as chairman in November.
