Worker put party above monarch (8)
I believe the answer is:
labourer
'worker' is the definition.
(labourer is a kind of worker)
'party above monarch' is the wordplay.
'party' becomes 'labour' (Labour Party is an example).
'above monarch' becomes 'er' (abbreviation for Elizabeth Regina, British Queen. I am not sure about the 'above' bit.).
'labour'+'er'='LABOURER'
'put' acts as a link.
Can you help me to learn more?
(Other definitions for labourer that I've seen before include "Navvy" , "Manual worker" , "He is said to be worthy of his hire" , "Hercules, perhaps?" , "One does heavy physical work" .)
