Campaigners against a new high-speed rail line from London to the Midlands will find out later if they've won a legal challenge to try and stop the £42 billion scheme going ahead.
Opponents of HS2 - including several Midlands councils - claim the project will be too expensive. A decision is expected at The Court of Appeal.
The MP for Chesterfield, Toby Perkins has dubbed the decision over where to build the high speed rail link 'amateurish'. It's after claims the maps used to choose the route were out of date.
The track, which links London to Leeds cuts across parts of Chesterfield canal.
But documents regarding the construction of the link, which were submitted to the government in March 2012, included maps which are missing nearby Staveley Basin which was built more than a year ago.
It's claimed the maps used to draw up the route for the new high speed rail link could be out of date.
The track, which links London to Leeds, cuts over stretches of the Chesterfield Canal.
But documents regarding the construction of the link, which were submitted to the government in March 2012, failed to include Staveley Town Basin that was completed more than a year ago.
It has also been claimed a 600 metre stretch of restored waterway is missing from the map.
Robin Stonebridge is from the Chesterfield Canal Trust.
Maps used to calculate the route for the High Speed Rail link could be out of date, say campaigners. The link between London and Leeds would cut straight through a new marina on the Chesterfield Canal, which isn't on the map of the route.
Transport Secretary Patrick McLoughlin has said that those who need to sell their house but struggle because of the HS2 plans will still be helped and that he wants the line, "to create jobs and prosperity not to harm it."
"I understand how proposals like this can affect the property markets so compensation will be as generous as on the first phase, and more generous then when we built the motorways."
Transport Secretary says that the HS2 will be first main line north of London for nearly 120 years.
Patrick McLoughlin has told the House of Commons that it is not just about faster trains to London - but about how our greatest cities are linked.
Mr McLoughlin said he is determined that HS2 benefits will be spread much wider than just those places served by the line.
The Prime Minister says the money to pay for HS2 will need to come from 'a balance' between the Government and 'the train user' - but expensive tickets are necessary for 'Britain to be a success'. See the full interview above.
The Prime Minister's team has tweeted this photo of a Cabinet meeting in progress at Leeds Museum to discuss "how billions will be invested in [the] Midlands and North, creating thousands of jobs".
David Cameron was resolute when asked about Tory opposition to the HS2 project: "This is going to happen. I have been a strong supporter right from the start." The Prime Minister continued:
A spokesman for Ladbrokes has said the firm is "not prepared to offer long odds" on the HS2 line being subject to delays, alterations and cancellations.
The bookmaker is currently offering 4/5 that there will be delays when it comes to the opening of the service.
The government expects to complete the first phase of the high speed route from London to Birmingham by 2026, with the Manchester and Leeds extension being finished by 2033.
