Despite pledging to find savings in the expensive High Speed 2 train line, the project's boss has failed to find significant financial cuts.
The Government has been accused in the Supreme Court of "cutting corners" to push through the HS2 national high-speed rail project.
The Government has hailed a "landmark victory" for its HS2 high-speed rail scheme, despite legal flaws in the consultation process.
Two Tory MPs are seeking to block laws that would pave the way for the controversial £50 million High Speed 2 railway, saying the line does not allow for construction to start from Leeds and Manchester.
Former minister Sir Edward Leigh (Gainsborough) and ex-whip Michael Fabricant (Lichfield) have tabled an amendment calling on the Government to bring forward a cheaper and more environmentally "sympathetic" route.
They warn the line as set out in the High Speed Rail (London-West Midlands) Bill is "significantly more costly" than it need be to reduce damage to the environment.
They also want MPs to stop the Bill from receiving a second reading as they say it fails to connect to HS1 and the Channel Tunnel, lacks public transport to disperse passengers at Euston and does not offer direct connections to existing major mainline train stations.
The rail route also fails to connect to potential airport hubs in London and the South East, according to the amendment.
People whose homes are blighted by the route or are subject to compulsory purchase orders are provided with "inadequate" compensation by the Bill, the MPs say.
The duo add the line is "insensitively routed" through previously unspoiled countryside, which will cause unnecessary damage to wildlife habits, waterways and ancient woodlands, plus does not allow for construction work to begin from Manchester and Leeds.
Sir Edward and Mr Fabricant do recognise there is a need for more north-south services to ease congestion on the West Coast Mainline and improve links between London and major cities.
The Bill is scheduled to have its second reading in the Commons on April 28, the first day after the Easter recess.
The HS2 link between London, the Midlands and the North of England is expected to cost £42.6 billion, which includes contingencies, with £7.5 billion for the trains.
The new boss of the controversial high-speed HS2 rail project says he wants it completed three years earlier than planned to bring economic benefits quicker to our region.
Sir David Higgins says improvements to the existing network are vital to compliment and feed into the proposed new HS2 stations in Leeds and at Meadowhall in South Yorkshire.
The north will face a "lost decade of growth" if recommendations to extend the early phase of HS2 are not accepted by politicians, a major rail union says.
Following Sir David Higgins' call to extend phase one of the project to Crewe, TSSA leader Manuel Cortes said: "Sir David is absolutely right - we cannot, as a country, take the slow line to a high-speed rail future.
"We need to make sure that the north benefits as quickly as the Midlands and the South from this huge investment.
The alternative, he said, is a "lost decade of growth while the South East powers ahead of the rest of the country with the lion's share of the budget".
"The £50 billion investment must benefit the whole country if it is to help re-balance the economy," Mr Cortes added.
The new head of HS2, Sir David Higgins, is due to outline later his recommendations for building the high speed rail link between London and Leeds for one and a half billion pounds less.
Demand on Britain's rail service is "growing at 5%" every year, the chief executive of HS2 told Daybreak.
Sir David Higgins said a completed HS2 line would cure a multitude of economic woes, including creating jobs, lure more businesses to the north and help create more space for passengers.
"No new railway lines north of London in 100 years - why should we put up with that? It's not fair on jobs that are created in the region."
Fares on the £50 billion HS2 high-speed line must be affordable and should be "broadly comparable" to those charged on other lines, rail industry chiefs said today.
There have been concerns that premium fares will be charged for those using the new high-speed line which is due to open in 2026.
Today, rail industry body the Rail Delivery Group (RDG) said "setting fares at the right level" was one of its five key priorities for HS2.
The RDG went on: "Prices should be broadly comparable with those on other sections of the network to ensure the new services are affordable and encourage more rail travel on HS2 and across the existing railway.
"Tickets for HS2 should be sold through the same national retailing outlets as for the existing network."
Legislation for the first phase is currently going through Parliament, with a second, Y-shaped, phase, taking the line to north west and north east England due to be completed around 2032/33.
Legislation to pave the way for the construction of the controversial HS2 rail link - which will link Yorkshire with London - is not likely to complete its passage through Parliament before next year's general election, Transport Secretary Patrick McLoughlin has indicated.
Failure to get the HS2 bill onto the statute book by the time of the May 2015 poll could make it a contentious election issue between the parties, particularly in constituencies along the route of the proposed line.
Questions were asked about Labour's commitment after shadow chancellor Ed Balls said there would be "no blank cheque" for HS2, though Ed Miliband has since reaffirmed his backing for the scheme.
Cross-party backing for HS2, which would run between London and Yorkshire has been thrown into doubt after Tory and Labour MPs from flood ravaged constituencies said they would refuse to support the £42 billion line unless improvements were made to the West Country railway network.
The prospect of a rebellion over HS2 from MPs of both parties was brought into sharp focus after Tory Gary Streeter, MP for South West Devon, said he would vote against it unless there was a firm Government commitment to properly replace the wrecked mainline at Dawlish in Devon.
Fellow Tory Neil Parish, MP for Tiverton and Honiton, who said he had so far "held his nose" when voting in favour of HS2 because he did not want to support it, said it was the duty of MPs in the far South West to stand up for their constituents.
Every MP in Devon, Cornwall and Somerset should sign up to Mr Streeter's position to send a "very powerful message" to the Government and Labour, which both support HS2, according to Labour former Cabinet minister Ben Bradshaw.
Mr Streeter said he had already told ministers he would vote against the HS2 hybrid Bill at second reading unless a proper commitment was made to the West Country.
The Chief Executive of HS2, the company which will build the new high speed rail link from the capital to the North has told Calendar - towns and cities across the region will benefit from the project.
Costing £50 billion, trains will run from London via, Birmingham, Sheffield and Leeds.
Alison Munro has been meeting local businesses in the area. She told Calendar HS2 would free up space on existing lines and bring investment opportunities:
