Former Cabinet minister Chris Huhne has pleaded guilty to perverting the course of justice over claims his ex-wife took speeding points for him a decade ago.

Huhne entered the plea on the first day of his trial at Southwark Crown Court.

His former wife Vicky Pryce denied a charge of perverting the course of justice.

Carina Trimingham, whom Huhne admitted having an affair with in 2010, ending his 26-year marriage to Pryce, was in the public gallery as he pleaded guilty to the perverting the course of justice charge.
