From a puppy farm to No.10: Boris Johnson's new rescue puppy Dilyn arrives at Downing Street

Boris Johnson and girlfriend Carrie Symonds have welcomed a 15-week-old rescue puppy from Wales into 10 Downing Street.

The Jack Russell, named Dilyn, had been abandoned by a Welsh puppy farmer before he was rescued by an animal charity.

Ms Symonds said the dog was about to be dumped by a puppy dealer because he was born with a crooked jaw.

She tweeted after being reunited with the dog to confirm he had been named Dilyn - which means 'follow' in Welsh.

The dog came from the Friends of Animals Wales charity, which said the "gorgeous pup will be living his best life with Carrie and the Prime Minister at their Downing Street home".

The Prime Minister's official spokesman said: "They are a fantastic charity run by volunteers who work around the clock to make a difference to animals.

"The Prime Minister has always been a passionate supporter of animal welfare and has always believed that animals should always get the right start in life."

Mr Johnson and Ms Symonds are hoping to raise awareness for new strict legislation which comes into force next April.

The legislation, known as Lucy’s Law, will ban the sale of puppies and kittens by a third parties and ensure that anyone buying or adopting one under six months old deals directly with the breeder or an animal rehoming centre, rather than a pet shop or commercial dealer.

Meanwhile, The Kennel Club says one in ten Welsh dog owners admit they may have bought a puppy-farmed dog.
