Clutching a metal ball and chain, small shops supporter Herbert Crossland is launching a new campaign to try to save historic King's Road antiques centre Antiquarius.

Antiquarius, a Grade II listed 1920s Temperance Hall, is home to numerous antiques traders in the heart of Chelsea. But it is set to become a fashion emporium called Anthropologie under plans set out by developers London & Associated Properties(L&AP).

Last month, long-term traders who have graced the building since the 1970s issued a plea for help in ensuring their futures.

Former Harrow borough councillor Mr Crossland, 61, answered their call and is now determined to rally residents behind the cause.

This Saturday, he will be collecting signatures from supporters of the King's Road centre, while holding a heavy ball and chain to represent the plight of traders 'shackled' to the whims of landlords.

"I want all the councillors and landlords to come down from 9am and 6pm and sign the petition to show their support for local businesses," he said. "I use the Antiquarius cafe and we've had enough. Landlords think they can do what they like."

L&AP has submitted plans to alter the interior of the specialist building but they have yet to be considered by Kensington and Chelsea Council.

A spokesman for the developers said: "We understand the sentiments being expressed but we want to work with traders and secure their future in the area.

"We've instructed agents and are prepared to assist traders in the early stages in getting into new premises.

"We are doing what we can to keep them close to the King's Road."

China trader Sue Norman, who has been at the centre since 1972, remains unconvinced. She said: "We're looking forward very much to being offered suitable alternative accommodation, but it hasn't happened yet."
