Seafront traders had to clear away broken glass after thousands of clubbers descended on Brighton beach for the Big Beach Boutique.

The Channel 4 sponsored concert drew 35,000 clubbers to hear city-based DJ Fat Boy Slim, but traders claim the morning after saw the beach strewn bottles and broken glass.

People setting up the popular Saturday market under the West Pier had to give first aid to one early morning walker who cut his foot when a shard of glass pierced his training shoe.

Norma Binnie, of the West Pier Trust, said more than 30 bottles were collected in the area around the pier, a few hundred yards behind the stage, and there was more that could not be retrieved.

She said: "The amount that was crunched into the pebbles, you are talking about at least 50 bottles and that is impossible to pick-up.

"I think the litter pickers were really out in force further along, where it was, and you could see it was mayhem."

Seafront trader Peter Avey, whose business is closer to the Palace Pier, said: "The only thing we have got over this side is the aftermath, the mess, bottles, rubbish, stuff knocked over and general chaos."

There was anger last summer following the Radio One Dance Party, when the beach was left covered in rubbish. The event was banned from returning this year because of the furore.

But Brighton and Hove City Council said it was satisfied with the clear up after Friday's concert and only one or two small patches had been missed.

Cabinet councillor Ian Duncan said Channel 4 had paid for litter pickers to start work as soon as Fat Boy Slim left the stage and work through the night.

He said it was impossible to stop people bringing bottles but events like the Big Beach Boutique should continue because they were good news for the city.

He said: "This is what we are about, it is what people are increasingly saying Brighton and Hove is bloody good at.

"No way will I be apologetic for putting on things like this, it is what gives the city its high profile."
