Look to follow Ofwat, say
I believe the answer is:
watchdog
'ofwat say' is the definition.
I can't judge whether this definition defines the answer.
'look to follow' is the wordplay.
'look to' becomes 'watch' (I can't explain this - if you can you should believe this answer much more).
'follow' becomes 'dog' (I've seen this before).
'watch'+'dog'='WATCHDOG'
Can you help me to learn more?
(Other definitions for watchdog that I've seen before include "Monitoring body" , "protector" , "Canine guard" , "Animal guard" , "Guardian (pet, official)" .)
