State Senate extremely reluctant (6)
I believe the answer is:
averse
'reluctant' is the definition.
(I've seen this before)
'state senate extremely' is the wordplay.
'state' becomes 'aver' (both can mean to declare).
'extremely' means to remove the middle letters.
'senate' with its centre taken out is 'se'.
'aver'+'se'='AVERSE'
(Other definitions for averse that I've seen before include "Not in favour of" , "Strongly opposed (to something)" , "Disinclined - as ever (anag)" , "Indisposed" , "Disinclined or reluctant" .)
