Government's leader in wrong job, one indicates (8)
I believe the answer is:
signpost
'one indicates' is the definition.
I can't tell whether this definition defines the answer.
'government's leader in wrong job' is the wordplay.
'leader' suggests taking the first letters.
'in' is an insertion indicator.
'wrong' becomes 'sin' (I've seen this before**).
'job' becomes 'post' (post is a kind of job).
The initial letter of 'governments' is 'g'.
'g' put into 'sin' is 'sign'.
'sign'+'post'='SIGNPOST'
Can you help me to learn more?
(Other definitions for signpost that I've seen before include "this will give you directions" , "Direction pointer" , "Indication of direction" , "director" , "Guide, indicator" .)
