Turned out they expressed disapproval following penalty notice and fine (11)
I believe the answer is:
tickettyboo
'fine' is the definition.
(I've seen this before)
'turned out they expressed disapproval following penalty notice' is the wordplay.
I cannot really see how this works, but
'disapproval' could be 'boo' (as in a crowd booing) and 'boo' is found within the answer.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for tickettyboo that I've seen before include "fine" , "OK" .)
