The Serious Fraud Office is probing the HS2 project after being handed a bombshell dossier of documents leaked by a whistleblower, The Mail on Sunday can reveal.
Investigators are understood to be examining allegations of corruption in the way some contracts may have been awarded to suppliers.
They are also examining claims that some homeowners and businesses on the route of the train network linking London and Birmingham with cities in Northern England may have been swindled out of large sums of money by being forced to sell up for unrealistically low prices.
A source with knowledge of the inquiry last night said SFO officials are ‘deadly serious’ about getting to the bottom of the claims.

They interviewed a major property owner for two hours last Wednesday after he also made a string of allegations about HS2 and are poring over documents leaked by a former senior HS2 executive.
‘They (the SFO) are deadly serious and they have got documents that came from a former executive. The stuff is lethal,’ said the source.
‘There are a lot of very good people in HS2 who feel their professional abilities have been impugned, their advice has been ignored and they have no wish to be tarred with this shambles that is about to break.’
The probe has sent shockwaves through the Department for Transport and is thought to have increased the likelihood that Ministers will pull the plug on the controversial scheme.
