Police have passed a file on Energy Secretary Chris Huhne to the Crown Prosecution Service in relation to allegations that he asked another person to take penalty points for speeding.
Mr Huhne's former wife Vicky Pryce claimed in a newspaper interview in May that the Eastleigh MP had tried to pass on his points to her in order to avoid losing his driving licence.
The speeding offence is alleged to have taken place in 2003 when the then MEP was driving home from Stansted Airport after flying back from the European Parliament. Mr Huhne has vigorously denied asking anyone else to take the points.
A spokesman for Essex Police said: "Essex Police can confirm that a file has been passed to the Crown Prosecution Service today."
The CPS must now decide whether any charges should be brought against Mr Huhne.
The CPS said the file - which relates to both Mr Huhne and Ms Pryce - will be assessed by a lawyer in its Special Crime and Counter-Terrorism Division, who will decide whether charges should be brought.
"We will look at it and then we will make a decision on whether anyone should be charged with anything," said a spokeswoman.
"We don't know how long it is going to take. It will depend on what is in the file. Depending on what is in the file, we may ask the police for more information or seek advice from counsel."
News that the file has been passed to police came as Mr Huhne was cleared of wrongdoing over his election expenses following an investigation by the Electoral Commission.
