THE controversial project to build HS2 is being put under the spotlight again after a report from KPMG reassessed the benefits.
The House of Commons Transport Committee will be questioning the transport secretary Patrick McLoughlin as well as KPMG on 26 November.
MPs want to scrutinise KPMG's assessment of the regional economic impact of HS2 and the strategic case for the project, which was published by the Government on 28 October.
The Committee has already published its own report on the project, but the latest figures from KPMG have now made parts of that report out of date.
The Committee's chair Louise Ellman said: "HS2 is a hugely significant and controversial investment. We are following up the questions we raised in our earlier report, in the light of significant new information."
HS2 will be managed by the present chief executive of Network Rail David Higgins from next year, and he has a brief to contain the project's costs.
However, Building Magazine has reported that the companies who are working on the preparatory stages of HS2 are already over budget.
Stop HS2 Campaign Manager Joe Rukin said; "We have always said that there is only one way which the costs for HS2 will go, and that is up, because so far ever single figure involved in HS2 has been pulled out of the air. Everyone knows that Government projects go massively over budget, and the Government think we will be filled with confidence because they have appointed someone with a track record of overseeing escalating costs to get the costs of HS2 down."
