County rubbish tip lacking room (9)
I believe the answer is:
bedsitter
'room' is the definition.
'county rubbish tip lacking' is the wordplay.
I cannot quite see how this works, but
'county' could be 'beds' (abbreviation for Bedfordshire) and 'beds' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for bedsitter that I've seen before include "Digs" , "One-roomed accommodation" , "Modest accommodation" , "pad" .)
