The former Energy Secretary Chris Huhne and his ex-wife Vicky Pryce are due to be sentenced today after she took speeding point on his behalf.
Huhne was served with a notice that he had been caught speeding on the M11 in Essex in 2003.
Huhne had already pleaded guilty to the offence, but Pryce denied the charge, arguing in court that she took the points under 'marital coercion'.
Her initial trial collapsed after the jury failed to understand the basic facts of the case and it's own role in proceedings.
Pryce was found guilty in the subsequent trial at Southwark Crown Court last week,
Nearly 10 years after his car was clocked speeding on the M11 in Essex, former energy secretary Chris Huhne could face prison for lying about who was behind the wheel.
His guilty plea today to a charge of perverting the course of justice was unexpected. Up until now he's denied that he was driving, falsely claiming that his ex-wife was responsible. Our report contains flash photography:

Former Cabinet minister Chris Huhne and his ex-wife are to stand trial next Monday over claims she took speeding points for him so he could avoid prosecution.
Huhne and his former wife Vicky Pryce were both charged last year with perverting the course of justice over the allegation, said to relate to a speeding offence in 2003.
Pryce previously pleaded not guilty on the grounds of marital coercion and Huhne today entered a not guilty plea to the charge.
The events which led to the charges date back to March 2003 when Huhne's car was allegedly caught by a speed camera on the motorway between Stansted Airport and London.
Both defendants are on bail and their trial at Southwark Crown Court is due to start next Monday.
Chris Huhne has hired Harry Redknapp's legal team to fight allegations that the former energy secretary perverted the course of justice.
It all stems from a claim that he asked his ex-wife Vicky Pryce to take penalty points after a speeding offence in Essex back in 2003 on his behalf.
The trial is expected to start in the summer.
