Calcutta Police initially confiscated meat for title holder (5)
I believe the answer is:
champ
'title holder' is the definition.
(I've seen this before)
'calcutta police initially confiscated meat' is the wordplay.
I cannot really see how this works, but
'police' could be 'mp' (abbreviation for Military Police) and 'mp' is located in the answer.
The remaining letters 'cha' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for champ that I've seen before include "boxer who is top dog?" , "Title holder (abbr)" , "use teeth?" , "Victor (slang)" , "Gnaw; winner (abbr.)" .)
