Two hours ago Newsnight discovered that Vicky Pryce - Chris Huhne's now estranged wife - was due to address a seminar at the LSE on the evening of 12 March 2003. That's the date in contention in the Chris Huhne speeding mystery.



And the LSE has just confirmed to me that Vicky Pryce did actually attend the event - a City Alumni seminar, starting at 6.30pm.

The organiser of the event, Nat Holtham, confirmed to me that Vicky Pryce spoke that evening, and that the event would have lasted between an hour and an hour and a half.

"I remember meeting Vicky and seeing her," he told me.

"I had been pleased to discover that one of our alumni held such an eminent position in government."

In itself, this fact proves nothing, but it makes it pretty unlikely that Vicky Pryce could have been driving in Essex beween 6pm and 8pm that evening.

Newspaper claims that Mr Huhne asked someone to take his penalty points for a speeding offence in 2003 emerged last week following a newspaper interview with Ms Pryce.

The Lib Dem cabinet minister has denied the allegation, describing it as "simply incorrect".
