Earls Court and Olympia Group (ECO) chief executive Andrew Morris, is to replace Jonathan Goold as Clarion Events managing director.
Goold, who recently quit the ECO in-house organiser (Marketing Event, Spetember), will work closely with Morris on a part-time basis until December and then work as a consultant to Clarion.
Morris will divide his time equally between the halls business and organising events and exhibitions.
He has already restructured the company into three divisions.
James Brooks-Ward is responsible for the trade division, Mark Saunders heads the consumer division and Victoria Borwick has control of the art and antiques arm.
'In assuming direct control of Clarion, I will be able to play a key role in delivering the company's ambitious growth targets and affect beneficial change more rapidly,' Morris said. 'The reorganisation will make Clarion more focused on the markets it serves and enable the teams to share and compare best practice.'
Meanwhile, Earls Court has opened its new Business Centre offering Internet access, email, workstations and stationery supplies.The facility is managed by Eforce.
