Careless hand of councillor seen in Poor Laws (6)
I believe the answer is:
scrawl
'careless hand' is the definition.
'scrawl' can be an answer for 'hand' (scrawl is a kind of hand). I'm not certain of the 'careless' bit.
'councillor seen in poor laws' is the wordplay.
'councillor' becomes 'cr' (I've seen this in other clues).
'seen in' is an insertion indicator.
'poor' indicates anagramming the letters.
'laws' with letters rearranged gives 'sawl'.
'cr' going within 'sawl' is 'SCRAWL'.
'of' is the link.
Can you help me to learn more?
(Other definitions for scrawl that I've seen before include "write hurriedly" , "Write carelessly or badly" , "Write untidily" , "Messy drawing, possibly" , "Write poorly, bad handwriting" .)
