Right-winger losing nothing in tax (3)
I believe the answer is:
try
'tax' is the definition.
(I've seen this in another clue)
'right-winger losing nothing' is the wordplay.
'right-winger' becomes 'Tory' (Tory is an example).
'losing' suggests deleting specific letters.
'nothing' becomes 'O' (looks like zero - 0).
'tory' with 'o' taken away is 'TRY'.
'in' is the link.
(Other definitions for try that I've seen before include "seek" , "Make severe demands on" , "Attempt; smooth (wood)" , "Test; attempt" , "A rugby score, result of effort" .)
