Queued to watch Prudential throw art away (5,2)
I believe the answer is:
lined up
'queued' is the definition.
('line up' can be a synonym of 'queue')
'watch prudential throw art away' is the wordplay.
I cannot quite understand how this works, but
'art' could be 'line' (line is a kind of art) and 'line' is present in the answer.
The remaining letters 'dup' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for lined up that I've seen before include "In a row" , "Arranged" .)
