The chief executive of Informa, the company behind Lloyd’s List, is to leave the company to head Emap’s business-to-business arm, but a proposed merger of Emap and Incisive Media is on hold, the Times and Telegraph reported this weekend.

Emap Communications was sold to a consortium of Guardian Media Group and the private equity firm Apax for £1.2bn last year. The new owners take formal control this week.

David Gilbertson, a former editor of Lloyd’s List, has been Informa’s chief executive since 1998. He is expected to take over as Emap’s chief executive. Current Emap Communications chief Derek Carter has not been offered another role under the new ownership, The Telegraph reports. Informa chairman Peter Rigby will this week be confirmed as its chief executive, says the Times.
