Newman said: "We are driving for clarity; in the past it has been very cloudy. We have got some fantastic projects and some great clients, but this has tended to get lost in the plc issues."
Despite the attempt to differentiate the parent company from its operating practice, Newman will retain his place on the board of Aukett plc. He was made a board director in June last year, having been at the group since 1981.
Ripoll took over the roles of chief executive and chairman after a vote at an extraordinary general meeting in March, where he placed a series of resolutions to replace members of the existing board. Ripoll, who is a major shareholder in the group, believed that the company was underperforming.
In a statement to the stock exchange, Ripoll said: "The appointment of a UK managing director is a key step for the group in its plans to move forward."
He is currently deciding his strategy for the group, and is considering transferring Aukett from the stock exchange to the alternative investment market.
