Common feature of publicity explicitly solicited within the law (5)
I believe the answer is:
licit
'within the law' is the definition.
(I've seen this in another clue)
'common feature of publicity explicitly solicited' is the wordplay.
'LICIT' is hidden in amongst the letters.
But, I'm not sure how this is indicated.
(Other definitions for licit that I've seen before include "Not forbidden, lawful" , "Lawful, permitted" , "Honest" , "Within the law" , "not banned" .)
