Choueke, who has worked for Centaur Media for four years, is thought to be taking a director-level communications role withing the Bell Pottinger Group.
It is understood that Choueke will start early in the New Year. Both Choueke and Bell Pottinger declined to comment.
Prior to joining Centaur Media, Choueke was a features editor on business title The Grocer and a business reporter for The Sunday Telegraph.
The news follows an uncomfortable couple of weeks for the agency after a series of revelations by The Independent newspaper.
The Independent printed an undercover investigation by the Bureau of Investigative Journalism that caught out trio of Bell Pottinger directors ‘secretly boasting about its access to the Government and how it uses the "dark arts" to bury bad coverage’.
Bell Pottinger was also accused of manipulation of Wikipedia entries from anonymous accounts linked to the agency. Lord Bell has since taken up an offer by Wikipedia’s founder Jimmy Wales to train his employees on the ethical use of the online encyclopedia.
