Labour MP for Hammersmith, Andy Slaughter, is leading a debate on a compulsory purchase order in relation to Shepherds Bush Market and the surrounding small businesses.
Orion Shepherds Bush Ltd got planning permission in 2012 for a plan to widen the market and build flats.
For the redevelopment, a compulsory purchase order has been made.
A parade of shops, a terrace of market units and two hostels would be demolished.
The developers say the £150m scheme will regenerate Shepherds Bush Market.
