Charlie has new pastime in temporary accommodation? (8)
I believe the answer is:
campsite
'temporary accommodation?' is the definition.
(place where people stay temporarily)
'charlie has new pastime' is the wordplay.
'charlie' becomes 'c' (phonetic alphabet: alpha, bravo, charlie etc.).
'has' means one lot of letters go next to another.
'new' is an anagram indicator.
'pastime' is an anagram of 'ampsite'.
'c'+'ampsite'='CAMPSITE'
'in' acts as a link.
(Other definitions for campsite that I've seen before include "Ground for tents" , "for temporary accommodation" , "Location for pitching tents" .)
