Shocking eastern chap with admissions of debt (9)
I believe the answer is:
egregious
'shocking' is the definition.
(I've seen this before)
'eastern chap with admissions of debt' is the wordplay.
'eastern' becomes 'e'.
'chap' becomes 'greg' (**).
'with' means one lot of letters go next to another.
'admissions of debt' becomes 'ious' (I've seen this in other clues).
'e'+'greg'+'ious'='EGREGIOUS'
(Other definitions for egregious that I've seen before include "Extraordinary" , "Outstandingly bad" , "Outstanding, outrageous" , "Outstandingly villainous" , "Shocking" .)
