Fears have been raised about the future staging of the Fox FM Party In The Park music festival.

The festival, featuring some of the country's biggest chart-topping acts, takes place annually on the first weekend in September at South Park, Oxford. But at Wednesday night's East Area Parliament meeting, city councillors and local residents expressed concern regarding the organisation of the event.

They said it was poorly organised in comparison to the park's other major music event last year, the one-off Radiohead concert on July 7.

Last year's Party In The Park, which featured pop acts Steps, A1 and Right Said Fred, attracted 15,000 people and cost about £70,000 to stage, including more than £15,000 to tidy up the site after the event.

But Margaret Miles, a resident of Cheney Lane, said: "We were caused inconvenience by the Radiohead concert, but when it came to the Fox FM event there was no organisation at all. We suffered during the concert and the litter afterwards was appalling."

Cllr Rob Sykes added: "The littering in several streets following the Fox FM concert was the worst I have seen after a South Park event."

Committee chairman Cllr Elise Benjamin suggested Fox FM should present a plan to the parliament to explain how they propose to manage this year's event better before they are allowed to run it.

The event is due to run in South Park this year on Sunday, September 1.

Council officer Fergus Lapage said he had been in contact with the director of Fox FM and the company had said organisation would be looked at and improved this year.

The parliament agreed to invite Fox FM to a future meeting so the radio station could present its plans.

Andrew Parsons, head of Oxford City Council's parks service, which helps organise the logistics of the event, said: "The events programme, including Party In The Park, is going ahead.

"The concerns of local people have been born in mind, and there are a lot of little things that have to be slicker."

Lyn Long, managing director of Fox FM, said: "Party In The Park is a fabulous and very popular free event for the people of Oxfordshire and west Buckinghamshire.

"We take very seriously all feedback given and always look to ways we can improve the event. We will be working extremely closely with all the services, including the council and emergency services."
