The estranged wife of Energy Secretary Chris Huhne attended an official dinner in central London on the same evening the beleaguered politician's car was caught speeding almost 40 miles away, it has been claimed.
According to reports, Vicky Pryce spoke at the London School of Economics (LSE) before enjoying a three-course meal on the night of March 12, 2003 - the same evening Mr Huhne's vehicle was clocked exceeding the 30mph limit on the M11 in Essex.
Police are considering whether to launch an investigation into allegations that the MP persuaded another person - named in press reports as being his wife - to take the resulting penalty points on his behalf.
It is reported in the Daily Telegraph that Mr Huhne may intend to tell officers that Ms Pryce was driving at the time of the alleged offence, and that any points which appear on her licence are her own responsibility.
But according to the Daily Mail, Ms Pryce is willing to stand up in court and testify against her husband.
A friend of the senior economist told the newspaper: "She was working in London during the day and evening of the date the offence took place in Essex. And she's quite prepared to stand up in court and say so if necessary."
Reports in the Telegraph claim that on the night in question, Ms Pryce addressed the LSE at 6.30pm, before attending a dinner which ended after 10pm, raising questions over whether it would be possible for her to be in Essex that evening.
Mr Huhne is understood to have flown from Strasbourg to Stansted that day, when the only direct flight arrived at the Essex airport at 10.23pm, said the paper.
It is not know at exactly what time the car was caught speeding.
More than a week after the story first surfaced in the press, Mr Huhne broke his silence on Monday to insist that the allegations are "simply incorrect". He added: "They've been made before and they've been shown to be untrue, and I very much welcome the referral to the police as it will draw a line under the matter."
