In place of holiday, English cleaner in criminal court! (4,5)
I believe the answer is:
cote dazur
'in place of holiday' is the definition.
(cote d'azur)
'english cleaner in criminal court' is the wordplay.
'english' becomes 'e' (abbreviation).
'cleaner' becomes 'daz' (UK laundry detergent brand).
'in' is an insertion indicator.
'criminal' indicates an anagram.
'e'+'daz'='edaz'
'court' with letters rearranged gives 'cotur'.
'edaz' put inside 'cotur' is 'COTE DAZUR'.
(Other definitions for cote dazur that I've seen before include "French Riviera (4,1'4)" , "Nice area" , "French Riviera region" , "Resort" , "strand of French" .)
