VICKY Pryce was today found guilty of perverting the course of justice by a jury at Southwark Crown Court.
The case before the jury proceeded against Ms Pryce following her taking a speeding ticket for her husband in 2003, to prevent him obtaining points on his licence.
Chris Huhne, aged 58, admitted his guilt on what was to be the first day of his trial on 4 February 2013.
Officers from the Kent and Essex Serious Crime Directorate were contacted in May 2011 with information regarding an offence of perverting the course of justice.
This was a thorough and complex investigation conducted by the Kent and Essex Serious Crime Directorate. Many of the records from 2003, such as cctv which may have confirmed either defendant's location on 12 March, had been unobtainable.
A black BMW activated speed camera at 23.23pm on 12 March 2003 on the London bound carriageway of the M11, at Chigwell, 550m south of the Luxborough Lane Road Bridge.
The vehicle was travelling at 69mph where the speed limit was 50mph.
A Notice of Intended Prosecution was duly sent which was returned stating that Vicky Pryce was driving the car at the time of the offence.
Ms Pryce disclosed to media that the driver of the BMW at the time of the speeding offence was Mr Huhne but that she had agreed to be named and take the points. This story was printed in newspapers in May 2011.
Huhne and Pryce were charged on 3 February 2012 with perverting the course of justice.
Assistant Chief Constable Gary Beautridge from the Kent and Essex Serious Crime Directorate said: "The conviction of Chris Huhne and Vicky Pryce has been achieved through the thorough and steadfast investigation conducted by officers and specialist staff at Essex and Kent Police. Perverting the course of justice is a serious offence.
"We hope this conviction serves as a timely reminder to motorists who try and avoid driving bans by 'giving' their points to others. This practice is not only unlawful, but has life changing consequences for those who get caught flouting the rules."
