News organisations have deplored new rules for the media for this year's Notting Hill Carnival.
The News Media Coalition (NMC), which represents the interests of major UK publishers and national and international news and photographic agencies, said coverage over many years had contributed to worldwide recognition of the event.
However organisers this year have sought to introduce charges for press access. They have also demanded that accredited media hand over material in addition to paying the £100 charge.
The NMC has written to the organisers objecting to the rules, seeking dialogue and also withdrawal of the fee for managed news access.
Andrew Moger, NMC executive director, said in a statement: "We strongly urge carnival organisers to rethink this policy, which can only serve to reduce interest. The success of the carnival as one of the most colourful cultural spectacles has come about through press and carnival and arenas working together. Unilaterally imposing new arrangements, costs and controls is not the way forward."
