Records describing campaign returned to lounge (6)
I believe the answer is:
sprawl
'lounge' is the definition.
(thesaurus)
'records describing campaign returned' is the wordplay.
'records' becomes 'lps' (LP is an example).
'describing' means one lot of letters goes inside another (describe can mean to form the outline of).
'campaign' becomes 'war'.
'returned' says the letters should be written in reverse.
'lps' placed around 'war' is 'lwarps'.
'lwarps' back-to-front is 'SPRAWL'.
'to' is the link.
(Other definitions for sprawl that I've seen before include "What stragglers do" , "Spread out in ungainly way" , "10 with one's limbs extended" , "Fall with limbs spread out" , "Loll, stretch out" .)
