Plans to transform the former MG Rover site at Longbridge into a £500 million mini-town with 1,400 houses, a shopping centre and a science park have been condemned as a "betrayal of everything Birmingham stands for".

The criticism came from Northfield Labour Party official and former regeneration cabinet member Andrew Coulson, who accused the city council leadership of breaking a promise made when Rover collapsed in 2005 to use the land as a centre for manufacturing.

Under a scheme drawn up by Birmingham City Council, Worcestershire County Council, Bromsgrove Council and landowners St Modwen, fewer than 3,000 manufacturing jobs and 2,759 high-tech jobs will be created over a 15-year period.

The remaining employment will be in the retail, office, distribution and warehousing sectors, bringing the total number of jobs to 10,000.

Housing, a new village centre for Longbridge and a superstore form the heart of the plans, which were launched by city council leader Mike Whitby last month.

Coun Whitby (Con Harborne) said the proposals would reinvigorate Longbridge's industrial heritage.

But Mr Coulson claimed the scheme was driven by short-term profit-making and he urged St Modwen to reconsider.

He added: "There is nothing original, no long-term vision. Nothing which uses the unique opportunities offered by a large area of brownfield land.

"The current plans demonstrate what happens when profit is king. They are a betrayal of everything Birmingham stands for - and at this time of goodwill St Modwen should withdraw these plans, and come back with imaginative ideas that will keep Birmingham great for at least the next 50 years.

"If it refuses to do so, the city council should refuse to accept them until such time as the commitment to use most of this unique site for manufacturing is reinstated."

Mr Coulson said a planned 1,000-space car park would be too small and urged the councils to plan instead for several thousand spaces linked to a new Longbridge Parkway railway station.

"A Longbridge Parkway, where mainline trains can stop as well as suburban services, could get large numbers of people to New Street and Moor Street in 20 minutes - and serve as the main park-and- ride station for commuters and visitors from the south and west."

Mr Coulson added: "There will be some manufacturing on the Longbridge land, especially now that Shanghai Automotive has merged with Nanjing - the assembly of modified MG TF roadsters from kits put together in China is better than nothing.

"A modest innovation centre and one building for small firms has been built but where are the tenants?

"Bournville College hopes to move onto the site, and will be welcome, but that is about moving jobs, not creating them."

Just over a third of the new houses at Longbridge will be "affordable homes", according to the councils.

But Mr Coulson said: "How many will there be for families of former Rover workers struggling on low wages and benefits? For single parents? For those getting older who want somewhere small and convenient to maintain?"

His comments follow similar criticism from Northfield Conservative councillor Reg Corns, who accused the council of back-tracking on a pledge to use all of the former MG Rover site for industrial and high-tech employment.

Northfield MP Richard Burden (Lab) said the success of the scheme would depend on building the local economy and making sure that young people currently at school could find employment.

"We must have jobs that are available to local people," Mr Burden added.
