Where records go in affair involving current ministers (6,7)
I believe the answer is:
filing cabinet
'where records go' is the definition.
(records might be stored in a filing cabinet)
'affair involving current ministers' is the wordplay.
'affair' becomes 'fling' (a fling is a romantic affair).
'involving' means one lot of letters goes inside another.
'current' becomes 'I' (symbol for electric current).
'ministers' becomes 'cabinet' (government ministers).
'fling' going around 'i' is 'filing'.
'filing'+'cabinet'='FILING CABINET'
'in' acts as a link.
(Other definitions for filing cabinet that I've seen before include "Item of office furniture" , "Where documents are found" , "Document storage unit" , "where records are kept" , "Piece of furniture containing documents" .)
