Clark, who has worked as a freelance journalist and broadcaster since leaving government, will in effect replace Simon Crine, who quit in January to join super regulator Ofcom as director for England.
APCO associate director Christopher Wainwright said Clark will report to the consultancy’s acting managing director Simon Milton until a new MD is recruited ‘in the very near future’.
Previous managing director Stephen Kehoe left to join Pepsico earlier this year.
Wainwright added that Clark’s experience as special adviser to former Foreign Secretary Robin Cook from 1997 to 2001 and his recent experience in journalism would be: ‘a bolster to our government relations team.’
Former press spokesman on the Microsoft anti-trust case Tom Brookes has quit APCO to join EU political consultancy GPlus Europe. Brookes has become account director at GPlus after having worked as a director at APCO’s Europe competition and media practice for the past two years.
He joins a team of 17 at GPlus where he will continue to work in his specialist areas of competition, telecoms, health and the media.
