In parliament, might he get round to making a collection? (4)
I believe the answer is:
whip
'parliament might he get round to making a collection?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'in' is the wordplay.
I cannot quite understand how this works, but
'in' could be 'hip' (both can mean fashionable) and 'hip' is found in the answer.
A single letter 'w' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for whip that I've seen before include "Strike with lash or rod" , "Person who enforces discipline in a political party" , "MP enforcing discipline" , "Riding crop" , "Instrument of punishment" .)
