MPs have warned Trade Secretary Alan Johnson not to allow the collapse of MG Rover to divert investment from other parts of the Midlands.
Staffordshire MPs met the Secretary of State to press for assurances that their constituencies would not be forgotten.
And they have asked Advantage West Midlands, the regional development agency, to provide a breakdown of exactly how much is spent in each constituency.
Paul Farrelly (Lab), the MP for Newcastle-under-Lyme, has asked the Department of Trade and Industry to provide a breakdown of exactly how much AWM spends aand where it spends it.
It follows the loss of 2,000 jobs over two years at Leoni Wiring, the largest employer in his constituency.
The meeting with Mr Johnson, which took place in the House of Commons, was organised by Stafford MP David Kidney ( Lab) and attended by MPs of all parties.
Mr Kidney said: "The specific issue in this case was the collapse of MG Rover, and the need to act as quickly as possible to support the area affected by that.
"While we all applaud that, we wanted assurances that it would not damage investment in Staffordshire. The Secretary of State was happy to give us that assurance."
Stoke South MP Robert Flello said: "When an issue like MG Rover comes up, we want to make sure the money being spent is as well as investment on other parts of the region, not instead of.
"It is simply a case of ensuring things are going in the right direction."
The Department of Trade and Industry has promised aid of £150 million to help Rover workers and local businesses, including £ 50 million for improving skills, £40 million for developing the Longbridge site and £50 million for business support.
