Plans to redevelop part of Portobello Road have been met with huge local opposition.
The Westway Trust charity wants to develop what it calls a tired and underused area.
But 15,000 people have signed a petition claiming the move will sanitise the famous vintage market.
London Live's Luke Blackall was there. He spoke to Phil Dibsdale, senior planning consultant for the Westway Trust, Lizzie Spring the owner of the Sew Portobello shop, who is against the plans and Maurice Nixon, owner of the area's vintage and fashion market.
