Admit NHS is struggling and inconsistent (3-3-4)
I believe the answer is:
hit-and-miss
'inconsistent' is the definition.
(I've seen this before)
'admit nhs is struggling' is the wordplay.
'struggling' is an anagram indicator.
'admit'+'nhs'+'is'='admitnhsis'
'admitnhsis' with letters rearranged gives 'HIT-AND-MISS'.
'and' acts as a link.
(Other definitions for hit-and-miss that I've seen before include "Haphazard" , "Inconsistent" .)
