They go to make several reforms (7)
I believe the answer is:
leavers
'they go to' is the definition.
The definition suggests an adverb but the answer is not.
'several reforms' is the wordplay.
'reforms' is an anagram indicator.
'several' is an anagram of 'LEAVERS'.
'make' acts as a link.
Can you help me to learn more?
(Other definitions for leavers that I've seen before include "They're off" , "Several (anag) -- Brexiteers" , "Those exiting" , "People departing" .)
