In yesterday's "i" crossword (originally in the Independent July 2016) one of the clues was:
Bun hairstyle, unfamiliar on celebrity, turning heads (4)
The answer was CHOU (anagram of first letters of "Hairstyle Unfamiliar On Celebrity").
I don't think I've ever seen this time of clue before and I didn't think they were allowed - you normally have initials, or an anagram, but not both. It seemed particularly unfair because the answer wasn't a very common word.
Do they crop up elsewhere?
