Chesham and Amersham MP Cheryl Gillan has warned that accelerating the delivery of HS2 risks heaping more misery on home and business owners in south Bucks.

Speaking yesterday, Mrs Gillan - whose constituency is set to be home to a large section of the phase one route - said the current legislative process for HS2 had been dominated by mismanagement and error from the company delivering the scheme.

Transport Secretary Patrick McLoughlin outlined revised plans for the near £56 billion project to MPs after being summoned to the Commons to answer an urgent question posed by Labour's Tristram Hunt.

HS2 boss Sir David Higgins proposed fast-tracking the £50 billion project last year and Chancellor George Osborne announced the speeded up plans yesterday.

The rail link was originally due to stretch from London to Birmingham by 2026, and then reach Manchester and Leeds by 2033.

Former Wales secretary Mrs Gillan said: "Despite the documents published today, over the past week alone we have seen the ombudsman finding HS2 guilty of maladministration over communications, the standing orders committee of this House describing their supply of information as an absolute shambles, and an FOI request from the Chesham Society revealing a massive inaccuracy in basic traffic assessments in my own constituency.

"What confidence can we have today's announcement of a speeded up timetable for phase two of HS2 is not going to lead to an increased catalogue of mismanagement, mistakes and more misery for people along the route?"

Mr McLoughlin replied: "The truth is anything I say about HS2 as far as you are concerned will not be met with any kind of favour whatsoever - you have made your opposition perfectly clear to it.

"I believe it is absolutely essential for the long-term economic interests of the United Kingdom and particularly for our northern cities as well.

"I do not dismiss those people who are directly affected by it and those people who have trouble as a result of a major infrastructure project taking place. I have seen no major infrastructure project which has ever got universal support in its time of construction - it has usually found that support afterwards."

Mr McLoughlin added: "The very first railway line which was going to be built between Birmingham and London was defeated in the House of Commons because the canals were perfectly adequate."
