ITV News Deputy Political Editor Chris Ship has been following the votes on the HS2 bill in the House of Commons.
MPs have now voted in favour of giving the legislation a second reading.
Campaigners who object to plans for a new high speed rail link on environmental grounds are talking "b*******" and only really care about their house prices, according to Mayor of London Boris Johnson.
Johnson claims that protesters "pretend" they are campaigning about woodland or wildlife but they are much more "furious" about the impact HS2 proposals are having on property values.
He suggested the Government should buy up the houses of the scheme's opponents for "top dollar", then when the rail link is finished, capitalise on any boost to local economies by selling them off for a profit.
Mr Johnson told Total Politics magazine: "People are in the humiliating position of having to pretend that there's some environmental objection that they have, that the great crested grebe is going to be invaded or whatever."
"What they care about is their house prices. It's tragic we have protest groups talking about 'this ancient woodland' when actually there's no tree in this country that's more than 200 years old.
"It's b*******. They're not campaigning for forests, they're not campaigning for butterflies. They pretend to be obviously, but what they're really furious about is that their house prices are getting it."
Around 500 wildlife areas could be at risk from the HS2 high speed rail line, conservationists have warned.
The Wildlife Trusts called for a £130m investment to create new green areas over the length of the new line.
Among the areas affected by the new line are 43 ancient woods and nine Wilflife Trust nature reserves.
Tory MP Michael Fabricant has been sacked as vice-chair of the party after criticising the HS2 rail scheme and Maria Miller over her expenses.
The former Conservative whip claimed on Twitter that he refused to resign so was sacked by party chairman Grant Shapps.
After news of Mrs Miller's resignation broke, the MP said: "Well, about time."
Mr Fabricant, MP for Lichfield in Staffordshire, tweeted this announcement:
Been asked to resign as Vice Chairman, refused, so sacked over HS2 and my views on a recent Cabinet Minister. Still available 4 speeches etc
After Mrs Miller resigned over her expenses scandal, he tweeted:
Note to self: If ever a minister again, be like Mark Harper. If in trouble, resign quickly & in a dignified manner. Lesson to us all.
He is set to lead a Tory revolt against the £50 billion HS2 scheme later this month by calling for laws so the London-Birmingham is denied a second reading in Parliament.
The MP has spoken of his shock at being sacked and wrote on Twitter:
The head of HS2 has said construction of the high-speed rail line should be speeded up, with a new hub in Crewe six years earlier than initially planned.
ITV News Deputy Political Editor Chris Ship reports.
Chancellor George Osborne has welcomed Sir David Higgins' recommendations for HS2, but warned there will be "no increases" in spending on the £50 billion poject.
Mr Osborne described the high-speed project as "essential to the future of this country".
However, he cautioned: "We must be conscious of the price, and there will be no increases to the overall spending envelope set for HS2 at the last spending review."
Earlier today, Shadow Transport Secretary Mary Creagh said there would be no "blank cheque" for the project.
Ms Creagh told BBC Radio 4's The World At One that Labour would be supporting the hybrid bill due to come before parliament but argued that the project had "suffered from mismanagement".
Plans to speed up the development of HS2 and extend it to the north more quickly have been backed by the government.
Asked whether the coalition would take action to accelerate the passage of the HS2 Bill through Parliament, Prime Minister David Cameron's official spokesman said: "We want it to proceed as quickly as it can, but it is obviously a very lengthy Bill."
Earlier today, Transport Secretary Patrick McLoughlin said Sir David Higgins' proposals for HS2 had the "strong support" of the government.
The government has also scrapped a proposed £700m scheme to link HS2 with the existing HS1 route to Brussels.
The government will instead look at other ways of linking HS2 with the continent.
HS2 link requires too many compromises in terms of impacts on freight, passengers and the community in Camden, says Transport Secretary.Read the full story ›
