This pig is for illustration purposes only and is not actually the fattest pig in Britain.

Two pigs at a farm in Cornwall have been given the enviable accolade of being Britain’s fattest pigs.

The animals, named Marjorie and Boris, have a combined weight of nearly three quarters of a ton and have lived on Chyvarloe Farm for a few years now.

While the pair were originally bought by the farmers Paul Parfitt and his wife Charlotte to fatten up and sell on, they have become so popular with their owners that they have been kept on as regular breeding mates.

Boris now weighs in at 420kg, while his mating partner Marjorie is a hefty 300kg. According to Mr Parfitt, the weight does not come from junk food and the pig has learnt to carry his weight well: “He never throws his weight around – he’s the most docile, laid back pig you’ll ever meet and he’ll happily let 100 schoolchildren line up and stroke him.

“He carries his weight really well – he’s a strong chap whose strength is hidden under rolls of fat. I’ve heard of pigs that weigh more than 450kg, but I reckon Boris is the podgiest porker in Britain.”

Boris looks to have secured himself a happy future as his owners have noted that he won’t be sold for meat anytime soon.
