Police document conflict in NHS, rat race ghastly (6,7)
I believe the answer is:
search warrant
'police document' is the definition.
'search warrant' can be an answer for 'document' (search warrant is a kind of document). I am not certain of the 'police' bit.
'conflict in nhs rat race ghastly' is the wordplay.
I cannot really see how this works, but
'conflict' could be 'war' (war is a kind of conflict) and 'war' is found within the answer.
an anagram of 'race' is 'earc' which is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for search warrant that I've seen before include "legal document" , "Permission to look for stolen goods" , "Police right of entry" , "permit to probe" .)
