Socialist hospital going wrong — that's a distraction! (3,7)
I believe the answer is:
red herring
'a distraction' is the definition.
(distracting false clue)
'socialist hospital going wrong' is the wordplay.
'socialist' becomes 'red' (socialism is often associated with the colour red).
'hospital' becomes 'h' (abbreviation for hospital on maps).
'going wrong' becomes 'erring' (I've seen this in another clue).
'red'+'h'+'erring'='RED HERRING'
'that's' acts as a link.
(Other definitions for red herring that I've seen before include "Irrelevant topic" , "An irrelevance" , "bait, of a certain sort" , "False lead" , "What distracts" .)
