Conservative leader suspended for being shifty? (8)
I believe the answer is:
changing
'being shifty?' is the definition.
('shifty' can mean 'changing')
'conservative leader suspended' is the wordplay.
'leader' indicates taking the first letters.
'suspended' becomes 'hanging' ('hanging' can be a synonym of 'suspended').
The first letter of 'conservative' is 'c'.
'c'+'hanging'='CHANGING'
'for' is the link.
(Other definitions for changing that I've seen before include "Altering" , "Switching" , "Fluctuating" .)
