Right bearing? Half guests don't follow suit! (7)
I believe the answer is:
renegue
'don't follow suit' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'right bearing? half guests' is the wordplay.
'right bearing?' becomes 'rene' (I am not sure about this - if you are sure you should believe this answer much more).
'half' suggests halving the letters.
'guests' cut in half is 'gue'.
'rene'+'gue'='RENEGUE'
Can you help me to learn more?
(Other definitions for renegue that I've seen before include "Rue gene (anag.)" , "Fail to fulfil an obligation" , "Break one's word" , "Welsh" , "Go back on one's word" .)
