Sees Vietnam's leader inside being charming (6)
I believe the answer is:
lovely
'charming' is the definition.
(I've seen this in another clue)
'sees vietnam's leader inside being' is the wordplay.
I cannot quite see how this works, but
'being' could be 'love' (love is a kind of being) and 'love' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for lovely that I've seen before include "Fair" , "Admirable" , "Beautiful (like money tendered in shop?)" , "Very nice -- coy elm (anag)" , "Great!" .)
