Organised gala in part of England (6)
I believe the answer is:
anglia
'part of england' is the definition.
'anglia' can be an answer for 'england' (I've seen this before). I am not certain of the 'part of' bit.
'organised gala in' is the wordplay.
'organised' indicates anagramming the letters.
'gala'+'in'='galain'
'galain' anagrammed gives 'ANGLIA'.
Can you help me to learn more?
(Other definitions for anglia that I've seen before include "Latin name for England" , "Old Ford and eastern England region" , "Eastern part of England" , "See 10" , "old car" .)
