One admitted to organisation, say, in debt leaving Britain - cue for reform? (8)
I believe the answer is:
inductee
'one admitted to organisation say' is the definition.
(someone inducted to an organisation)
'in debt leaving britain cue for reform?' is the wordplay.
'leaving' is a deletion indicator.
'britain' becomes 'B' (common abbreviation as in GB).
'for reform?' indicates an anagram (I've seen this in other clues).
'debt' with 'b' taken out is 'det'.
'det'+'cue'='detcue'
'detcue' is an anagram of 'ductee'.
'in'+'ductee'='INDUCTEE'
(Another definition for inductee that I've seen is " One formally admitted (to an organisation)".)
