Intrusive photographers capturing Queen for tabloids? (6)
I believe the answer is:
papers
'tabloids?' is the definition.
(tabloid is a kind of paper)
'intrusive photographers capturing queen' is the wordplay.
'intrusive photographers' becomes 'paps' (short for paparazzi).
'capturing' is an insertion indicator.
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'paps' enclosing 'er' is 'PAPERS'.
'for' acts as a link.
(Other definitions for papers that I've seen before include "Documentation" , "Print media" , "tabloids, maybe" , "Documents; the press" , "ID etc." .)
