For the second time this year police were called to move on anti-Tesco demonstrators after a similar incident involving protestors in Stokes Croft, Bristol.
The supermarket is facing growing pressure to abandon plans to open a new store on the site after Caroline Lucas, the Green MP for Brighton Pavilion, added her voice to the opposition. She is currently campaigning for a reform in the planning regulations to better protect independent stores. Another Tesco store would devastate local shops, she said.
She plans to meet with Tesco bosses later this month to discuss the plans, which involve a mixed-use development of residential and retail units.
The garden, which was established on a derelict forecourt site, was widely used by local residents, but protestors have no legal claim to the land.
"The garden is a well-loved feature and people don't want or need another chain supermarket," Lucas said.
