See British Shorthair cat for a description of this breed generally.
I share the same thoughts about the wrong perpetrated on the Persian cat by a combination of the cat associations, judges and in some cases the Persian cat breeders in developing a hopelessly ill conceived cat breed, the extreme type Persian.
"With the British cat having been rescued from near extinction in World War II by having been outcrossed with the Persian, perhaps it's time for the Longhaired variant of the Brit to repay this breed's war debt by offering its services as an outcross with a fully functional muzzle and healthy respiration in order to rescue the deliberately disfigured Persian from being genetically engineered into extinction by those entrusted with its care."
"When one looks at the British Longhair it is easy to imagine that this is a cat the poor Persians would dream of being."
The point is that this breed could rehabilitate the Ultra type, extreme, Persian and maybe it is time that this happened. It would complete the circle. The flat faced extreme Persian should look like the British Longhair.
Finally, as mentioned, the only other cat association other than TICA to recognize the British Longhair cat is the World Cat Federation (good for them). Here is a brief summary of the breed standard from the WCF:

Head: rounded, massive and broad; short nose; short muzzle.
Ears: medium in size.
Eyes: large and round.
Coat: medium/long, dense and smooth, undercoat, crisp, ruff desirable, bushy tail.
Colors: "All colours and point colours without white are recognized"
