Plans to remove running of the West Coast Main Line from Virgin Trains will go ahead, despite growing opposition from some MPs and members of the public.
The Government is set to sign off the controversial 13-year deal tomorrow (August 29) - the deal will see winning bidder FirstGroup take over the line, which runs through the North West.
Transport Secretary Justine Greening said despite the Commons Transport Select Committee wanting to examine the new deal, FirstGroup and the Government will press ahead with the deal.
Speaking on BBC Breakfast this morning, Mrs Greening said all bidders had "bought into" the "fair and well-established process".
A row has raged over Virgin losing its franchise and boss Sir Richard Branson offered to run the route free of charge to allow the decision to be re-examined.
The Labour Party is also urging Mrs Greening not to sign off the contract until MPs have been able to scrutinise it in detail.
More than 100,000 members of the public have signed an online petition against the decision, in a campaign supported by double Olympic champion Mo Farah, Apprentice star Lord Sugar and celebrity chef Jamie Oliver.
Sir Richard has urged the Prime Minister to "intervene to try to get some sense into the Department for Transport", saying with Mr Cameron and the Chancellor George Osborne away on holiday, a decision on signing the deal should be delayed by a month.
