Regrets changes involving India’s official list (8)
I believe the answer is:
register
'official list' is the definition.
(I've seen this before)
'regrets changes involving india's' is the wordplay.
'changes' indicates anagramming the letters.
'involving' is an insertion indicator.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'regrets' anagrammed gives 'regster'.
'regster' placed around 'i' is 'REGISTER'.
(Other definitions for register that I've seen before include "Record book" , "Log" , "Class roll" , "Enrol, to vote perhaps" , "Official record of names, transactions" .)
