Getting one's fair share to eat, after clinching English league (10)
I believe the answer is:
federation
'league' is the definition.
(I've seen this in another clue)
'getting one's fair share to eat after clinching english' is the wordplay.
I cannot really understand how this works, but
'share' could be 'ration' (a ration is a share of a limited resource) and 'ration' is found in the answer.
'english' could be 'e' (abbreviation) and 'e' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for federation that I've seen before include "Russia, for one" , "Group of states" , "Union of states" , "Alliance" .)
