Chris Huhne will attempt to carry on as normal today despite allegations threatening to destroy his political career about a speeding fine that may have been blamed on the wrong driver.
Essex Police confirmed that they have been handed information that could lead to a criminal investigation into the Energy Secretary's past.
A spokesman said: “We are aware of allegations regarding a speeding offence in 2003. This information will be passed to officers who will decide on whether an investigation will be launched.
His aides continue to deny the allegations which — if true — would destroy any hope he has of replacing Nick Clegg as leader of the Liberal Democrats.
It is alleged that when Mr Huhne was sent a form to fill in about an automatic speeding fine he had incurred in March 2003 and he entered another person's name instead of his own, to avoid a driving ban.
He has hired an eminent media lawyer, Charlotte Harris of Mishcon de Reya, to handle the allegations, which Mr Huhne denies.
