The Department for Transport has strongly denied suggestions that the HS2 rail project could be delayed or scrapped completely.
An article in The Spectator magazine suggested it could be the end of the line for the scheme and opponents have already welcomed the idea.
The high speed rail link would cut through swathes of countryside in Buckinghamshire and Oxfordshire.
Campaigners against the project say it won't offer value for money.

It may be a bit early to start hanging up the bunting just yet, but it is becoming increasingly clear that HS2 is running out of supporters because the case for it has simply been made up around the idea that those three words ‘high speed rail’ sound like they must be a good idea. It is getting clearer and clearer that we have always been right and there is no business case, not environmental case and clearly no money to pay for HS2."
Mr Rukin added: "The Prime Minister talks about wanting to join the high speed revolution and if he wants to do that, he has two choices, either go down the line of bankruptcy like The Netherlands and Spain, or follow the example of Belgium, Poland and Portugal and cancel this white elephant before it is too late."
But today, a spokesman for the Department for Transport said there no question of any delay on the project._

There has been no change of heart and no change of policy. We continue to work towards the business plan."
Fifteen local councils launched a legal challenge in April against the decision to go ahead with the rail link.
