Vicky Pryce has said Chris Huhne refused to step down from office over his affair because "(late Labour minister) Robin Cook didn't have to".
After confessing, she said Huhne told her he had 20 minutes to write a statement, then left her and her son at the house to go to the gym.
"At no time was there an apology or any concern about what it would mean for us," she told Southwark Crown Court. "He ran out, with us following behind, and said, 'and don't talk to the papers'. We were left with no information about the whole business, and then newspapers descended upon us."
