David Cameron has new companion for catching rats - Larry

British Prime Minister David Cameron has welcomed a cat named Larry to Downing Street. The cat, aged between three and five, was chosen after a delegation from Downing Street went to Battersea Cats Home and staff from the home carried out a suitability check on No 10.

The cat's job is to deter the rats reportedly spotted in the building. He will be allowed to roam in No 11 too.

The prime minister's spokesman said the cost of the upkeep would not be met by the taxpayer, according to The Guardian.

David Cameron welcomed the tabby's arrival. The PM said: "I'm delighted to welcome Larry to his new home. He came highly ­recommended to me by Battersea Dogs and Cats Home, who did a fantastic job looking after him. "I'm sure he will be a great ­addition to Downing Street and will charm our many visitors," Mirror.co.uk reports.
