The guilty verdict means both Price and Huhne, who pleaded guilty to perverting the course of justice as his trial was about to start, face time in prison, The Daily Telegraph reported. The couple are to be sentenced together this month.
A jury in Southwark Crown Court deliberated for 11 hours before finding Pryce guilty of the same crime as her husband. An earlier trial ended with jurors unable to agree on a verdict.
The scandal ended Huhne's political career. In 2007, he came close to winning leadership of the Liberal Democrat Party and he was named secretary for the environment and climate change in the coalition government in 2010. But less than two years later, he became the first British Cabinet minister forced out of office by a criminal charge and he resigned from Parliament this year when he entered his guilty plea.
Pryce went public with her story about helping her husband avoid a license suspension during the couple's bitter divorce. During the trial, she claimed she was a victim of marital coercion.
