Bond hero putting on weight, heading for bar during conference? (10,4)
I believe the answer is:
paddington bear
'bond hero' is the definition.
(character created by Michael Bond)
'on weight heading for bar during conference?' is the wordplay.
I cannot quite see how this works, but
'on' is within the answer.
'during' could be 'in' (I've seen this in other clues) and 'in' is found within the answer.
This may be the basis of clue (or it may be nonsense).
'putting' is the link.
(Other definitions for paddington bear that I've seen before include "Original character from Peru" , "Visitor from Peru" , "is what some children love" , "Bond character" , "Children's favourite" .)
