Renate Zylla, director of the Berlinale's Children's Film Festival (Kinderfilmfest), has tendered her resignation, less than a fortnight after Wolfgang Jacobsen's announced he was stepping down as the organiser of the festival's Retrospective.

Zylla had worked for the Kinderfilmfest in Berlin since 1985 and was appointed the sidebar's director in 1988. She is understood to have resigned prior to going on holiday and the exact reasons behind her decision are still unknown.

German press reports of cost-cutting at the Kinderfilmfest prompting the move were denied by Berlinale press officer Frauke Greiner as "totally false."

A meeting between Zylla and Berlinale director Dieter Kosslick is planned for next Tuesday (August 20) - when she returns from holiday to discuss the reasons for her resignation.

Meanwhile, the Berlinale has confirmed that the UK's Simon Perry has stepped down as a member of the festival's 13-person film selection committee which advises Kosslick on the selection for the Official Competition. There are no plans to find a replacement for Perry.
