Christine Hemming, wife of Liberal Democrat MP John Hemming, is charged with burgling the Birmingham home of Emily Cox, a researcher with whom her husband fathered a child in 2005.
It is alleged that the burglary took place at night on September 29.
Christine Hemming, 52, of Moseley, Birmingham was not required to enter a plea during her appearance in court on October 21. The senior partner with the recruitment agency Diverse City Services was granted bail and will appear for a committal hearing on December 16.
The Daily Express
reported that it understood examination of CCTV footage formed part of the police inquiry.
In an online blog the Birmingham Yardley MP posted photos of the missing kitten, who is called Beauty. He states that the kitten, a short-haired tabby, is about six months old and belongs to his daughter (Isabel), who is five this month.
“If anyone has seen this kitten please contact me at the House of Commons. There is a reward for its return,” he said in the blog
After it was made public that the MP was going to have a child with Cox, his wife – who had had three children with - said she would stand by him but added the six-year affair was "about number 26."
She later supported her husband in his efforts to become leader of the Liberal Democrat party.
"I was upset when I first heard about his affair with Emily Cox, just as anyone would be," The Telegraph
reported that she had previously said.
"It was an unfortunate incident and I wish it hadn't happened, but we are making the best of the situation. We have got a healthy baby who is an addition to our family. I have seen her on a number of occasions."
John Hemming has described his domestic status as "an unclear situation."
In 2004, Cox became the Lib Dem member representative for Moseley and Kings Heath on Birmingham City Council.
