Leave those with possessions to retain large share (2,6)
I believe the answer is:
go halves
'share' is the definition.
(I've seen this before)
'leave those with possessions to retain large' is the wordplay.
I cannot really see how this works, but
'leave' could be 'go' (to go is to depart or leave) and 'go' is found in the answer.
'large' could be 'l' (eg in clothes sizes) and 'l' is located in the answer.
'those with' could be 'haves' (I've seen this in another clue) and 'haves' is found within the leftover letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for go halves that I've seen before include "share all costs" , "To follow the Dutch method" , "Share equally" .)
