The Liberal Democrats have vowed to halt the sale of the a former school in Gloucester should they take control of Gloucestershire County Council at the elections in May.
The Conservative-run county council want to build 90 houses on the former Bishop’s College off Estcourt Close in Longlevens.
But the Lib Dems say the sale should be halted until a full review has been carried out into secondary school provision in the north of Gloucester.
The Lib Dems, who are the second largest party on the county council, are bidding to take control and oust the Conservatives after 12 years of rule at Shire Hall.
Councillor Jeremy Hilton, Lib Dem county councillor for Kingsholm & Wotton, said: “There is no comprehensive school in the north of the city.
“Every day 2,000 children leave Gloucester to attend comprehensive schools outside of the city boundary. This is a ridiculous situation.
“With more than 14,000 new homes planned in the Gloucester area and most of these in the north as suggested in the Joint Core Strategy, we must agree a site for a new comprehensive secondary school to serve all these extra families.
“The sale of the Bishops College site must be halted.”
In September last year Gloucester City Council’s planning committee granted outline planning permission for 90 houses on the land, subject to conditions.
The city council website suggests that a decision notice has yet to be issued.
Local resident Linda Castle, who is the Lib Dem county council candidate for Longlevens, said: “There is a dire need for a brand new comprehensive secondary school to serve Longlevens and the north of Gloucester.
“Children attending secondary school in the future should have the same opportunity as I had and be able to go to a local school that’s within walking distance.
“I was saddened when my former secondary school in Paygrove Lane was closed down. I’m angry with the Tories who now want to build on the Bishop College site.
“It would make an ideal location for a new comprehensive school. We must have proper review of secondary school provision.”
