BoJo's right wing view (7)
I believe the answer is:
opinion
'view' is the definition.
(I know this)
'bojo's right wing' is the wordplay.
'right' suggests the final letters (the letter on the right of the word).
'wing' becomes 'pinion' (synonyms).
The last letter of 'bojo' is 'o'.
'o'+'pinion'='OPINION'
(Other definitions for opinion that I've seen before include "Personal belief or judgment" , "Unproved belief or view" , "impression" , "Point of view or thought on something" , "Belief not founded on proof or certainty" .)
