MPs from across the Midlands opposed to HS2 have lodged their objection in advance of a Commons debate tomorrow.
They've signed an amendment asking that legislation paving the way for HS2 be halted until the full details are known about the route and the cost.
Among the objectors is Stafford MP, Jeremy LeFroy.
An influential group of MPs says the DfT has failed to present 'a convincing strategic case' for HS2.
Campaigners say they hope to put plans for HS2 through the Midlands back to square one as they prepare to go to the High Court tomorrow.
Campaigners from HS2 Action Alliance are heading to London tomorrow to take on the Government at the Court of Appeal.
