Land in south Birmingham at the centre of a battle between two retail giants is to be sold by the city council to the highest-value bidder.
Both Tesco and Helical, the development partner of the Midlands Co-operative Society, want to buy the half-acre site off Hazelwell Lane, in Stirchley.
Tesco wants to build a superstore on the land, while Helical intends to construct a non-food shopping centre with high-profile tenants to include Matalan, PC World, Currys and JJB Sports.
Both prospective developers say their scheme would regenerate Stirchley as a shopping destination.
However, Helical has warned a successful bid by Tesco would threaten the viability of a nearby Co-op supermarket, which has been in Stirchley for 150 years.
Tesco has already gained planning permission for its scheme, while Helical is in the process of doing so.
Co-op bosses accused the council of fast-tracking the Tesco application, while dragging their feet over the Co-op proposal.
Both Tesco and Helical are bidding to buy the city council-owned land, which includes an indoor bowling facility and a community centre. The site is owned by several different organisations, including the city council.
Tesco has already secured options to buy about 80 per cent of the site.
A report to next week's council cabinet meeting recommends that a competitive process is used to decide which scheme should get the land.
A council spokeswoman said the merits of the respective schemes and the likely regeneration benefits would be measured as part of the process, as will the deliverability of the schemes. The developers will also be asked to demonstrate how they will replace the community centre and the bowling facility.
Cabinet member for regeneration Coun Ken Hardeman (Con Brandwood) said: "This is a key site that everyone wants to see developed, both for the new facilities it will bring and for the local regeneration benefits. With two companies bidding for our land, we feel that this competitive process is the best way forward."
