Party with little hesitation shows hand (8)
I believe the answer is:
labourer
'hand' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'party with little hesitation' is the wordplay.
'party' becomes 'labour' (Labour Party is an example).
'with' says to put letters next to each other.
'little hesitation' becomes 'er' (expression of hesitation).
'labour'+'er'='LABOURER'
'shows' acts as a link.
Can you help me to learn more?
(Other definitions for labourer that I've seen before include "Hercules, perhaps?" , "He is said to be worthy of his hire" , "One is worthy of his hire, according to the Bible" , "Workman" , "Navvy" .)
