Could George Osborne's cat be the purr-fect spy? "Some of us think the Chinese got her," said one Conservative source. She can get everywhere. You'd only have to bug her to find out half the Government's secrets. She has been described as the "purr-fect" spy because of her ability to get past policemen and protection officers. It has led to her being discovered in the most secure area of the Foreign Office, inside the Cabinet room in Number 10, trying to break into the Treasury and in the command centre during a Royal Navy exercise. In contrast David Cameron's cat Larry spends his days lazing outside Number 10. Sources have even suggested to the Chancellor that Freya may be using him for his top secret political knowledge. She is not the first Downing Street cat to have mysteriously disappeared. When Tony Blair's cat Freya went missing shortly after the election in 1997 some blamed Cherie, but officials insisted she had simply retired.
