Eva's husband had the right to interrupt a labourer (5)
I believe the answer is:
peron
'eva's husband had' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'right to interrupt a labourer' is the wordplay.
'right' becomes 'r' (common abbreviation).
'to interrupt' means one lot of letters goes inside another.
'a labourer' becomes 'peon' (peon is a kind of labourer).
'r' going into 'peon' is 'PERON'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for peron that I've seen before include "Surname of Evita of the musical" , "Former Argentine leader" , "Former Argentinian leader" , "Juan, maybe" , "Argentinian dictator, 1946-55" .)
