Claire Jenkinson has quit her role as head of conference business Emap Networks, only six weeks after the announcement of the restructure of Emap's publishing, information and events business.

Emap chief executive David Gilbertson reorganised the business recently after it was acquired by Guardian Media Group and Apax Partners earlier in the year.

The magazines division was renamed Emap Inform and is now led by Simon Middelboe, while the exhibitions and festivals division, including the Cannes Lions Advertising Festival, was renamed Emap Connect and is now run by Malcolm Gough.

Emap's data division was renamed Emap Insight and is headed by Neil Bradford, the chief executive of fashion information business WGSN.com, and by Rupert Keane, the chief executive of the company's other data businesses.

Gilbertson also renamed the conference division Emap Networks, which had Claire Jenkinson at the helm before her recent resignmation.
