The first pic is quoted elsewhere on the net as being some German rabbit, not any British one. Anyway it looks more like a bear than a rabbit, I really think it's a hoax.
Noticed that, too.
It could be a hoax, but I think it's rather the camera angle that makes that animal look indeed monstrous.
I really doubt its weight can be 22KG, though, that would rather be a pig.
The result of a very strange biological experiment perhaps - a cross between a pig and a bunny...
(no, it's not possible, btw).
