Lowercasing of acronyms is a common stylistic choice made by UK media to aid readability. "Where you would normally pronounce the abbreviation as a string of letters - an initialism - use all capitals with no full stops or spaces (eg FA, UNHCR, NUT). However, our style is to use lower case with an initial cap for acronyms where you would normally pronounce the set of letters as a word (eg Aids, Farc, Eta, Nafta, Nasa, Opec, Apec)."
